摘要: 滚筒洗衣机的振动问题一直是产品改善的重点,悬挂系统是滚筒洗衣机常用的减振措施。以滚筒洗衣机悬挂系统为研究对象,首先利用ADAMS建立悬挂系统的虚拟样机模型,对虚拟样机仿真结果进行验证分析,与试验结果在转速稳定阶段振幅基本保持一致,说明了仿真模型的有效性;然后基于Box-Benhnken的中心组合试验设计原理设计正交试验表,通过方差分析确定吊簧刚度系数、减振器阻尼系数、上配重块质量与下配重块质量对悬挂系统振幅影响显著;最后利用多元回归分析与响应面法优化得到最佳结构参数组合,优化后的悬挂系统振幅减小14.8%,说明了该优化方法的有效性。

Abstract: The vibration problem of cylinder washing machine has always been the focus of product improvement, and the suspension system is a common vibration reduction measure of cylinder washing machine. Taking the suspension system of cylinder washing machine as the research object, firstly, the virtual prototype model of suspension system is established by ADAMS, and the simulation results of virtual prototype are verified and analyzed. The amplitude is basically consistent with the experimental results at the stable speed stage, which shows the effectiveness of the simulation model. Then, based on Box-Benhnken’s central composite experimental design principle, the orthogonal experimental table is designed. Through variance analysis, it is determined that the stiffness coefficient of spring, damping coefficient of damper, mass of upper counterweight and mass of lower counterweight have significant influence on the amplitude of suspension system. Finally, multiple regression analysis and response surface method are used to optimize the optimal structure parameter combination. The optimized suspension system amplitude decreases by 14.8%, which shows the effectiveness of this optimization method.
