某行星齿轮减速器箱体改进研究

针对某行星传动齿轮减速器振动大的问题,通过振动测试,得到减速器的固有频率和振动速度频谱图,发现造成减速器振动偏大的原因,进而运用有限元分析软件寻求有效的改进方案.根据测试结果,对有限元计算模型进行反复修正,最终掌握了合理的有限元建模分析方法.通过对减速器箱体进行结构改进,采用验证过的有限元分析方法进行减速器固有频率计算,最终确定了对箱体进行结构改进的有效方案.

Study on the Improvement on the Case of Certain Planetary Reducer

To solve the poor vibration of certain planetary reducer,the author gets the natural frequency and vibration velocity diagram of the reducer,and then detects the reasons.The author recurs to the software of finite-element analysis to get the betterment method.According to the results,the author finally gets the reasonable method of simulation analyses through repeated amendments.Using the method,the paper finally ascertains the effective improvement method on the case of planetary reducer by calculating nat...
