关于客户
CalsonicKansei North America (CKNA) 隶属于全球汽车零部件制造商 CalsonicKansei Corporation(总部位于日本)。该公司生产各种汽车零部件,包括内部驾驶舱和中控台。 CKNA致力于开发高端、创新产品,不断提高成本竞争力。为了实现这些目标,他们不断发展和改进其开发流程。计算机辅助工程 (CAE) 在这种能力中发挥着巨大作用。 CAE 的使用可以提高质量并缩短时间。
挑战
CalsonicKansei North America (CKNA) 是全球汽车零部件制造商 CalsonicKansei Corporation 的一部分,总部位于日本,该公司面临着汽车内饰吱吱声 (S&R) 的挑战。这个问题影响了他们的产品质量和客户满意度。尽管在现代计算机辅助工程 (CAE) 技术方面经验丰富,但 CKNA 尚未充分探索在物理硬件生产之前使用仿真技术研究 S&R 问题的潜力。吱吱声和嘎嘎声是当组件的两个零件由于特定的激励负载而相对运动时发生的两种现象。对 S&R 方法知识的缺乏阻碍了早期问题检测,导致产品完成效率低下和潜在的保修索赔。
解决方案
CKNA 联系 Altair ProductDesign (PD) 寻求 Squeak & Rattle Director (SnRD) 培训,这是一套全面的自动化软件,可快速识别和分析设计方案,以消除装配中吱吱声和嘎嘎声的根本原因。随着时间的推移,两家公司决定共同努力以取得更重大的进展。 Altair 能够提供 SnRD 以及对吱吱声和嘎嘎声方法的深入了解,以更好地帮助 CKNA 将其仿真结果与正在开发的产品的实际性能相关联。 Altair 提供了此类分析所需先决条件的观点,包括应使用哪些建模技术、如何提高有限元 (FE) 模型的保真度、应应用何种类型的载荷、哪些方法适合相关和预测,这次合作产生了联合驾驶舱项目,建模、仿真和测试结果分析的每一步都由两家公司携手完成。
运营影响
  • With Altair PD’s help on the cockpit project, CKNA was able to recognize how their existing FE models could be improved in the frame of the SnRD process, enhancing the fidelity and better capturing the reality. This was beneficial for S&R analysis but also improved the correlation for other load cases like Frequency Response Analysis, which is part of standard load cases performed by the CKNA CAE team. Altair was also able to provide tailored scripts to jumpstart a robust process at CKNA, including how to create loads from frequency to time domain and the method of correlating between test and simulation data. The new process included the consideration of material data and damping as well, both pieces which were lacking in their process before. CKNA learned how using SnRD to detect squeaks and rattles earlier in the development process can improve the overall final product design. CKNA can now cut project development time considerably and potentially gain more clients than previously possible by adding the squeak and rattle CAE based prevention methodology and simulation capability to their portfolio of services.
