| 摘 要： | RV减速器是工业机器人的核心零件，针对我国生产的减速器寿命短、噪声大等缺点，研究其动态特性意义重大。模态特性是研究动态特性的基础，是研究的第一步。论文建立有限元模型，对RV减速器中的主要部件进行模态仿真，仿真结果和实验结果相差不到5%，在误差范围内，验证了仿真结果的可靠性以及有限元模型的准确性；用Bush单元简化轴承，施加约束后对整体进行模态分析，前三阶固有频率远大于啮合频率，说明工作状态时在外部激励下结构共振的可能性小，为后续研究结构的动态特性提供参考。

| Abstract: | RV reducer is the core part of industrial robot. It is of great significance to study the dynamic characteristics because RV reducer produced in our country has a short life and high noise. Modal characteristics are the basis and the first step of studying dynamic characteristics. This paper establishes the finite element model of the main parts and completes modal simulation. The deviation between simulation and experiment is less than 5%, which means the accuracy of the finite element model and simulation results .Simplify bearing as bush element to connect the whole structure.The first three order natural frequenciesare far greater than the meshing frequency.There is no possibility of resonancein the external incentive. The whole works provide a reference for the further research of the dynamic characteristics of structure. |
