用UG NX软件的三维建模功能设计出了某洗碗机防震垫的模型，用其高级仿真模块对该防震垫进行了有限元分析，发现了应力和变形存在的不足。用UG NX软件的优化功能，以满足应力变形为优化条件，模型相关尺寸为优化目标，进行了优化计算，并对优化结果进一步验证，发现优化后的产品符合应力变形指标要求。此方法缩短了设计周期，为类似产品设计提供了一种可靠的设计方法，有参考价值。

Dishwasher antivibration pad model was designed using the three-dimensional modeling function of Unigraphics NX software. Finite element analysis was carried out on the antivibration pad using its advanced simulation module. Deficiencies in stress and deformation were found. The optimization was carried out with the target of model size optimization under the condition of meeting stress and deformation requirement by using the optimization function in UG NX software. The optimization results were verified. The results showed that the optimized products meet stress and deformation requirements. This approach can shorten design cycle. The purpose was to provide reference for similar product design.
