摘要
由于动平衡机在检测动不平衡量及去重时,精度不能满足要求,为了提高其动态特性,对动平衡机平衡摆动部件进行分析与改进。采用有限元模态分析方法计算其固有频率及振型,由于第1阶模态振型不符合要求,通过设计多种方案进行改进,最后提出了一种有效解决其振型不一致的方法,实现了振型的一致性。实践证明了该方法的可行性,动平衡机检测精度获得了提高。可为同类型部件设计提供参考与借鉴。
When the dynamic balance machine test the dynamic unbalance number and to weight it, the accuracy can not meet the requirements, in order to improve the dynamic characteristics, the balancing swing part of dynamic balance machine carries on the analysis and improvement. Using the finite element modal analysis method to calculate its natural frequency and mode, there are several schemes designed, because the first mode does not meet the requirements, then we find an effective method to solve the problem. Finally, practice has proved the feasibility of this method, detection accuracy get improved, The technology can be referenced for the same types of component.
