关于客户
一个多世纪以来,福伊特驱动沙芬贝格一直与铁路行业的质量和安全息息相关。公司不断的技术改进和技术更新使“Schaku”成为全球最著名的铁路车钩系统之一。从轻轨车辆到高速列车,该公司拥有超过 500,000 个车钩在使用,赢得了客户的高度信任。如今,福伊特驱动夏芬伯格的系统解决方案涵盖了列车前端的全系列吸能组件,包括运动学和控制电子设备。该公司的产品适用于任何应用,并且非常适合其用途,始终领先于时代一步,坚定地关注乘客和火车的安全。
挑战
Voith Turbo Scharfenberg 是铁路行业的领导者,面临着设计轨道车车钩的挑战,该车钩可以吸收火车碰撞时产生的巨大能量,从而提高乘客的安全。能量吸收系统必须满足特定标准,不仅在严重撞击期间,而且在列车平稳运行或轻微撞击期间也必须有效运行。吸收系统的组件,特别是橡胶元件,在碰撞过程中会发生很大的变形,这使得这些超弹性材料的模拟成为一个挑战。此外,还必须满足吸收元件的特定非线性力路径特性。基于不同碰撞场景模拟的设计评估对于优化耦合器及其能量吸收特性是必要的。
解决方案
Voith Turbo Scharfenberg 利用 ANSYS Mechanical 软件对外壳和吸收元件之间的复杂接触行为以及橡胶元件之间的接触进行建模。该软件的标准接触公式用于解决模拟超弹性材料的挑战。测试结果的特征力路径曲线用于调整超弹性材料行为。分析了多个负载场景,以提供足够的负载组合来充分评估设计。使用 ANSYS Mechanical 可以在 ANSYS Workbench 中简单快速地设置高度非线性分析,从而简化了开发过程。 ANSYS Workbench 中的超弹性材料可用于 ANSYS Mechanical 仿真,并且可以采用标准接触设置,而不会出现收敛问题。

Remote Temperature Monitoring of Perishable Goods Saves Money
RMONI was facing temperature monitoring challenges in a cold chain business. A cold chain must be established and maintained to ensure goods have been properly refrigerated during every step of the process, making temperature monitoring a critical business function. Manual registration practice can be very costly, labor intensive and prone to mistakes.

Leveraging the IoT to Gain a Competitive Edge in International Competition
Many large manufacturers in and outside Japan are competing for larger market share in the same space, expecting a growing demand for projectors in the areas of entertainment, which requires glamor and strong visual performance as well as digital signage that can attract people’s attention. “It is becoming more and more difficult to differentiate ourselves with stand-alone hardware products,” says Kazuyuki Kitagawa, Director of Service & Support at Panasonic AVC Networks. “In order for Panasonic to grow market share and overall business, it is essential for us to develop solutions that deliver significant added value.” Panasonic believes projection failure and quality deterioration should never happen. This is what and has driven them to make their projectors IoT-enabled. More specifically, Panasonic has developed a system that collects data from projectors, visualizes detailed operational statuses, and predicts issues and address them before failure occurs. Their projectors are embedded with a variety of sensors that measure power supply, voltage, video input/ output signals, intake/exhaust air temperatures, cooling fan operations, and light bulb operating time. These sensors have been used to make the projector more intelligent, automatically suspending operation when the temperature rises excessively, and automatically switching light bulbs. Although this was a great first step, Panasonic projectors were still not equipped with any capability to send the data over a network.
