摘　　要：本文以无配重滚筒洗衣机为分析对象,根据洗衣机振动产生原理,建立数字化几何模型,采用有限元解析法对无配重滚筒洗衣机振动情况进行模拟分析。解析结果显示外筒模块在水平方向上振动位移过大,本文提出了在外筒前部两个减震器之间增加一个横向减震器的解决方案,并通过振动解析,确认方案有效;最后按照国家标准通过整机测试验证了此方案的减振效果达到了标准要求。本文对业内人士研究滚筒洗衣机振动控制方面提供了一定的参考价值。In this paper,the drum washing machine without balance weight as the research object,According to the principle of washing machine vibration generation,a digital geometric model is established,and the vibration of washing machine without balance weight is simulated and analyzed by finite element analysis method.The analytical results show that the vibration displacement of the outer-tub module is too large in the horizontal direction.In this paper,a solution to add a transverse shock absorber between the two shock absorbers in the front of the outer-tub is proposed.Finally,through the whole machine test,the damping effect of the scheme meets the standard requirements according to the national standard.This paper provides some reference value for the study of vibration control of drum washing machine.
