• Das MMI (Materialmodellierung, mechanische Berechnung und Spritzgusssimulation)-Team für fortgeschrittene Simulationstechnologien bietet erheblich verbesserten Service für PA6-GF-Werkstoffe
• Integrative Simulationsumgebung lässt sich effektiv mit der Digimat-Software anwenden und gewährleistet präzise und robuste Finite-Elemente-Analysen

DOMOs fortschrittliche Simulationsumgebung MMI für PA66-Bauteile gilt auf dem Markt bereits als Referenz für präzise Simulationen. Ab sofort unterstützt dieses Simulationstool OEMs und Bauteillieferanten bei der Entwicklung von leistungsfähigen, leichten und kosteneffizienten Bauteilen aus PA6. Mit dem DOMO Service Hub können Bauteilentwickler ihre Polyamidlösungen somit schneller in Serie bringen.

Bei glasfaserverstärkten Materialien muss die Ausrichtung der Glasfasern berücksichtigt werden, die während des Spritzgussverfahrens entsteht. Dabei ermöglicht die Digimat-Software eine genaue integrative Simulation. DOMO besitzt ein umfangreiches Fachwissen bei der integrativen Simulation der TECHNYL® A-Serie von PA66-GF-Materialien und ist daher in der Lage, präzise Bauteilsimulationen durchzuführen.

Die neuen MMI-PA6-GF Materialkarten können für eine Vielzahl von Glasfaserkonzentrationen und -temperaturen sowie für elastische und elastoplastische Materialmodelle mit Versagensindikatoren eingesetzt werden. Diese sind in der Digimat Software verfügbar und führen zu den gleichen präzisen Ergebnissen wie bei den TECHNYL® A PA66-Werkstoffen. Die neuen Materialkarten heben somit die PA6-Datenbank auf das gleiche Leistungsniveau wie PA66 an. Im nächsten Schritt werden in die Digimat-Datenbank auch crashspezifische und thermische Modelle eingepflegt.

„Dank der präzisen MMI-Simulation können TECHNYL® Bauteile entwickelt werden, die leichter, leistungsfähiger und kosteneffizienter sind“, erklärt Gilles Robert, Material Expert bei DOMO. „Unsere Kunden profitieren von kürzeren Entwicklungszeiten und haben eine bessere Kontrolle über die internen Kosten. Der kontinuierliche Aufbau der TECHNYL®-Materialdatenbank erweitert das Anwendungsfeld dieser Simulationsumgebung auf PA6 Bauteile.“

SHIMA SEIKI ITALIA S.p.A., Italian subsidiary of leading Japanese computerized knitting solutions provider SHIMA SEIKI MFG., LTD., will exhibit at the 90th edition of the Pitti Immagine Filati exhibition in Florence, Italy. Products exhibited will include the N.SVR®123SP computerized flat knitting machine as well as APEXFiz™ design software.

The N.SVR®123SP computerized knitting machine features a special loop presser bed, capable of producing hybrid inlay fabrics with both knit and weave characteristics. Demand for such novel fabrics are very high across a wide range of applications, from fashion apparel to sportswear, innerwear, outerwear, uniforms and other functional clothing, as well as home furnishing and technical textiles. Shown in 18G at the SHIMA SEIKI booth, N.SVR®123SP will also feature the special i-Plating option, capable of alternating yarn colors in any pattern, producing jacquard-like designs using plain jersey stitch. Plating can be performed within the same course and for individual needles. In combination with the loop presser and spring-type moveable sinker system even greater diversity in knit design is possible. An SVR®123SP machine in 14G with i-Plating option will also be on display at the booth of yarn spinner IAFIL S.p.A. as well.

APEXFiz™ is subscription-based design software that maintains the proven functions that have made SHIMA SEIKI’s SDS®-ONE APEX series design systems so popular with fashion designers. Installed on personal computers, those strengths are now enhanced with the added versatility to adapt to different work styles and business environments including teleworking and telecommuting. APEXFiz™ software supports the creative side of fashion from planning and design to colorway evaluation, realistic fabric simulation and 3D virtual sampling. Virtual samples are a digitized version of sample making that are accurate enough to be used effectively as prototypes, replacing physical sampling and consequently reducing time, cost and material that otherwise go to waste. APEXFiz™ thereby helps to realize sustainability and digitally transform the fashion supply chain.

APEXFiz™ along with SHIMA SEIKI’s yarnbank™ digital yarn web platform are featured at a special section launched at the previous session of Pitti Filati no. 89 called Pitti Studios. Pitti Studios is a content production service that yarn companies exhibiting at Pitti Filati can use for their own promotion. Yarn companies provide a piece of yarn, which is digitized on yarnbank™ and used to simulate photorealistic fabric on APEXFiz™. This is then processed by a creative studio specializing in digital content to provide static and animated 3D virtual representations. The process shows how to use the latest DX tools to provide accurate representation of a finished garment without having to produce any fabric, converting the conventionally wasteful process of sample-making into a sustainable one.

Continuing from past editions of Pitti Filati are knit samples produced in collaboration with Italian designer Vittorio Branchizio.

Picanol has introduced its latest generation of airjet and rapier weaving machines, which have been called the “Connect” generation. These new generation weaving machines focus on connectivity and an increased level of data availability. With this new generation, Picanol is launching several new functionalities such as a digitalized Gripper stroke setting, Gripper tape monitoring, Climate control, Shed angle measurement, and fully integrated Power monitoring.

“Following the successful launch of our digital platform PicConnect earlier this month, we have now released a new generation of weaving machines, which are known as the Connect generation. Our Connect generation weaving machines can provide the correct data and are loaded with new and never-before-seen functionalities. This is clear proof that for Picanol “Driven by Data” is not just a slogan but a commitment. Not only have these innovations allowed us to make big improvements when it comes to our four design principles – Smart Performance, Sustainability Inside, Intuitive Control, and, of course, Driven by Data – but when combined with our new digital platform they will allow you to amplify your own intuition.” comments Johan Verstraete, Vice President Weaving Machines.

From now on, the range of Picanol weaving machines will have the “Connect” suffix. For the airjet weaving machines, this means: OmniPlus-i Connect and TerryPlus-i Connect, while for the rapier weaving machines, this means: OptiMax-i Connect and TerryMax-i Connect. These new machines are built around Picanol’s four main design principles:

Smart Performance
On the OptiMax-i Connect, Picanol has introduced a lubrication monitoring sensor in combination with a temperature sensor. The combined data they provide allow the user to make sure the gripper tapes are in optimal condition for maximum performance. As an option, a gripper stroke measurement sensor is also available. This not only dramatically simplifies the setting of the gripper stroke, but also enables the user to realize higher machine speeds when weaving reduced widths – a pure extra output combined with more user-friendliness.

Sustainability Inside
Even though it was 25 years ago that the Sumo Drive concept was launched, it remains the most powerful, versatile and energy friendly machine drive available. And it has been even further optimized. It features an optimized sheet metal package for lower energy consumption, optimized oil cooling circuit for a better performance and a built-in temperature monitoring. Moreover, the Connect machines can be equipped with a Power monitoring module, which allows the user to keep track of the power consumption of each machine over time. Every Connect machine also has a built-in ambient temperature and humidity sensor, which will help to optimize the climate control in the weaving shed at the lowest cost. And as raw material is the biggest cost factor, each machine can also be equipped with raw material use monitoring.

Driven by Data
As the machine has more sensors than ever before, it also generates more data. To enable a fast reaction to all these sensor data, the BlueBox control unit has been further optimized: better heat management guarantees short reaction cycles combined with the long lifetime of components. To have a good view of all of the data generated, a special sensor dashboard screen is available in the BlueTouch display: with a simple touch of the screen, the current and historical power consumption, temperature, humidity, material consumption, and – on the OmniPlus-i Connect – also the air consumption, can be monitored. The BlueTouch display is now also equipped with an Action center, an electronic logbook where all actions such as maintenance interventions can be logged or scheduled beforehand. The machine manual is now available on the BlueTouch display, and with the context-based help function the help pages related to the operation the user wants to perform appear with one touch of his/her fingertip. The built-in web browser even allows the user even to consult, for example, tutorial videos on the web to guide them through a setting procedure.

Intuitive Control
The Connect generation was designed to focus on what really matters: weave the highest possible grade A fabrics at minimal costs. A large set of tools have been installed to facilitate this goal. One of the most remarkable ones is the Harness frame stroke measurement – until recently, it was only available on the revolutionary SmartShed, but it is now also available on the cambox and dobby machines. Combined with the shed visualization and simulation, it offers a quantum leap in terms of optimizing the user’s shed settings without losing any time or taking any risks. The colors of the programmable Smart signal lights with stop timing functionality are now repeated around the push buttons, allowing even better visibility and the prioritization of interventions by the weaver. A full-fledged Access control system not only limits the access to certain pages and settings depending on the user, but also allows a tailored dashboard to be established for each user profile.

Global energy consumption reached a record high in 2019, following a 40-year trend for rapidly increasing energy demand that was only halted by the Coronavirus pandemic. It’s estimated that more than 80 % of this energy is still generated from fossil fuels that produce CO2 emissions and contribute to climate change. Renewable energy offers a solution to this problem, but saving energy whenever possible is an even more effective approach. That are the motives for Trützschler to develop the intelligent card TC 19i, which sets a new benchmark for energy-efficient carding.

The intelligent Trützschler card TC 19i features the unique T-GO gap optimizer, which continuously and automatically monitors and adjusts the carding gap to an ideal position during production. Innovative drive- and air technology further reduce energy consumption of the TC 19i.

The most energy-intensive elements in a carding machine are the drive, the dust suction process and the compressed air system. Permanent suction is needed to remove dust and cotton waste in key places. Smart optimization of these areas has made the intelligent card TC 19i a benchmark for energy efficiency in carding because it uses less electricity, lower suction pressure and less compressed air than other machines, while providing the highest production rates currently available on the market.

In a head-to-head comparison between the TC 19i and a high-performance card from a competitor, the TC 19i consumed at least 10 % less energy per kilogram of material produced when manufacturing rotor yarn from a cotton and cotton waste mix. The compared energy values included electric power consumption and energy required for suction and compressed air and were measured in both cards at the same production of 180 kg/h. A 10 % reduction in energy per kilogram of sliver produced, as proven here by TC 19i, can have a significant impact on a spinning mill’s profitability; annual savings worth a five-digit sum are frequently possible, depending on factors such as the output of the mill. The customer trial also showed TC 19i’s excellent reliability at the customer’s usual production rate of 180 kg/h, and even demonstrated stable performance at 300 kg/h in the same application. Because the TC 19i with T-GO gap optimizer realizes maximum production rates at no compromise in quality, manufacturers can reduce their energy demand and investment costs drastically: Less machines are needed to achieve the desired output, and energy consumption per production is reduced.

This improvement was made possible by a long and sometimes challenging innovation process involving mathematical models of air flows, as well as flow simulations and prototypes. By combining the final flowoptimized parts in the TC 19i, Trützschler’s experts have developed a card that operates with suction pressure of just -740 Pa and with an air requirement of only 4200 m³/h. This translates into 40 % less energy demand for air technology compared to the latest high-performance competitor model.

Angesichts globaler Megatrends wie Elektromobilität und Nachhaltigkeit steigen die Anforderungen an das akustische Design von Fahrzeugen. Simulationssoftware und computergestützte Entwicklung – computer-aided engineering (CAE) – verbessern nicht nur die Akustikleistung, sondern sollen auch den Entwicklungsprozess neuer Modelle beschleunigen. Durch die Zusammenarbeit mit dem Softwareunternehmen Free Field Technologies (FFT) fließen Autoneums Simulationsmethoden im Bereich Fahrzeugakustik in die Modellierungssoftware Actran von FFT ein, womit neue Standards beim CAE- Design des NVH-Verhaltens (Noise, Vibration, Harshness) und Datenaustausch erreichbar werden.

Autoneum und FFT haben ihre Expertise in der Entwicklung innovativer und nachhaltiger Methoden im Bereich Fahrzeugakustik bereits in zahlreichen gemeinsamen wissenschaftlichen Aufsätzen unter Beweis gestellt. Im Rahmen ihrer Partnerschaft werden die beiden Unternehmen ihre Synergien künftig auch dafür nutzen, bestehende Prozesse und Workflows im Akustikdesign weiter zu optimieren, zu standardisieren und zugleich die Modellierung von NVH-Materialien wie auch den Datenaustausch zwischen Fahrzeugherstellern und Zulieferern zu verbessern. Die präzise Berechnung der akustischen Fahrzeugleistung früh im Entwicklungsprozess erlaubt es, Design- und Vorlaufzeiten deutlich zu reduzieren sowie das Verhältnis zwischen Leistung, Gewicht und Kosten der lärmdämmenden Materialien zu optimieren.
