摘　　要：基于有限元理论实现某型全自动洗衣机在跌落冲击载荷下的仿真分析和设计改进。首先运用CAD软件Unigraphics(UG)建立洗衣机运输包装件的初始设计模型,然后将实体模型导入有限元软件Abaqus建立有限元网格模型并进行跌落仿真分析。分析结果表明跌落过程中箱体部件会发生起皱变形缺陷,仿真预测结果与试验结果吻合良好。针对当前设计中存在的问题,对洗衣机进行了局部改进设计和重新分析验证。改进设计后的洗衣机整机强度得到了有效增强,满足了跌落试验要求。这种"基于仿真的设计方法"为家电产品开发提供了一种新的有效手段。The dropping simulation and design improvement of a washing machine were conducted based on finite element（FE） analysis.An initial design model for a washing machine was established using the CAD software Unigraphics.Then,its FE model was set up and the dropping analysis was performed with the FE software Abaqus.The simulation results showed that wrinkling and deformation of parts of the machine body occur in the dropping process.The predicted results agreed well with the test ones.The initial design of the washing machine was modified and the analysis was performed again.The improved design made the washing machine have stronger strength and meet the requirement of dropping test.This simulation-based design approach provided a new and effective means for the further development of household appliances.
