挑战
日本华尔卡工业公司是一家领先的工业填料和垫圈制造商，它面临着延长焊接波纹管使用寿命的挑战。波纹管由一个折叠框架组成，该框架由从波纹板切割而成的精致金属盘组成，其内缘和外缘交替焊接。焊接波纹管具有弹性和气密性，用于密封应用，例如半导体行业的超高真空阀、晶圆加工设备和单晶生长器，以及航空航天飞行器使用的陀螺仪、蓄能器和阻尼器。为了延长使用寿命，优化由焊接部件组成的波纹板的形状至关重要。对于在焊接部件上/周围承受集中反作用力的焊接波纹管的设计，制造最适合分散这种集中反作用力的波纹板至关重要。
关于客户
日本华尔卡工业公司是日本领先的工业填料和垫圈制造商。该公司生产的产品种类繁多，包括橡胶、纤维产品、高性能树脂和金属填料。他们的一款主打产品是“焊接金属波纹管”，它由折叠成手风琴形状的框架组成，框架由波纹板切割而成的精致金属盘组成。这些板的内边缘和外边缘交替焊接，使波纹管具有弹性和气密性。这些波纹管用途广泛，包括用作半导体行业超高真空阀的密封件、晶圆加工设备、单晶生长器，以及航空航天飞行器中使用的陀螺仪、蓄电池和减震器。
解决方案
日本华尔卡从整个波纹管模型中创建了一个具有三个波峰的波纹板模型，作为要分析的轴对称模型。对于此分析，它应用了使用参数设计的优化方法。在此阶段，日本华尔卡将指定波纹板波纹形状的圆弧和其他因素参数化。随后，它使用 ANSYS 软件进行分析。对于此分析，使用 ANSYS 参数化设计语言 (APDL) 自动执行一系列过程 - 从使用参数更改模型形状到存储分析结果。考虑到大多数波纹管断裂发生在焊接部分上/周围，日本华尔卡根据获得的分析结果探索了冯·米塞斯应力增加的可能原因。结果，它从这些原因中找到了对应力增加产生重大影响的参数。
