摘要
为实现滚筒洗衣机的轻量化设计,通过CAE仿真计算分析皮带轮采用玻璃纤维增强热塑性复合材料替代铸铝材料的可行性。在分析过程中选择PP+50%GF塑料为替代材料,通过初步的结构设计、有限元模型建立、确定计算边界和工况后,进行仿真计算最大变形量和应力,根据计算结果优化结构设计,最终计算结果表明复合材料皮带轮的变形量和应力均符合标准要求,实现轻量化(减重14.9%)同时可实现降本20%,具有替代的可行性。
In order to realize the minimization of the drum washing machine,the feasibility of replacing the cast aluminum material with fiber-reinforced thermoplastic composite material for the pulley was analyzed through CAE simulation calculation.In the analysis process,PP+50%GF plastic was selected as the substitute material.After the preliminary structural design,finite element model establishment,and calculation boundary and working conditions were determined,the maximum deformation and stress were simulated and calculated,and the structural design was optimized according to the calculation results.The final calculation results show that the deformation and stress of the composite material pulley meet the standard requirements,and the weight reduction of 14.9%and cost reduction of 20%can be realized.The replacement is feasible.
