| 摘 要： | 利用有限元理论,对某承受动态载荷产品中的关键支撑件棗支架建立了有限元模型,并进行模态分析,计算了前六阶模态参数(固有频率和模态振型)。通过与试验模态分析的方法获得的模态参数相比较,证明计算结果是合理的,提出了对结构的修改意见以提高结构的动态特性。

| Abstract: | According to the theory of finite element,the finite element model of the bracket ,a key supporting part in a product subjected to dynamic load, is established for modal analysis and the first six order modal parameter,including natural frequencies and viberation modes, is caculated.By comparing the caculated result with the experimental result,the caculated result is proved to be reasonable.Finally, some structure modifications are made to improve the dynamic behaviour of the bracket. |
