| 摘 要： | 以RV减速器为研究对象,建立了RV减速器的三维模型,导入Adams中进行运动学仿真,得到了正齿轮的加速度;利用ANSYS Workbench求解得到RV减速器的固有频率,根据概率统计学分析技术推导功率谱密度函数;最后,将功率谱密度峰值提取后导入ANSYS Workbench的Random vibration模块作随机振动分析。该方法考虑了随机振动因素对机构应力以及安全裕度的影响,为处理RV减速器工作可靠性问题提供了一种新的方法。

| Abstract: | Taking the RV reducer as the research object,the 3Dmodel of RV reducer is established.Then,it is imported into Adams for kinematic simulation,and the acceleration of spur gear is obtained.The natural frequency of RV reducer is solved by ANSYS Workbench,and then the power spectral density(PSD)function is derived according to the probabilistic statistical analysis technology.Finally,the peak power spectral density is extracted and imported into the Random vibration module of ANSYS Workbench for random vibration analysis.This method considers the influence of random vibration factors on the stress and safety margin of the mechanism,and a new method for solving the reliability problem of RV gear reducer is provided. |
