摘要
建立圆柱齿轮副三维啮合模型,通过定义接触对的方式对其进行有预应力的有限元模态分析;在模态分析的基础上,应用Newmark-β法分析了齿轮副在不同啮合刚度下的动态响应以及不同阻尼条件下的频谱变化,分析结果可为齿轮传动系统的优化设计提供有力的技术参考。
The prestressed finite element modal analysis is carried out by defining contact pair based on a cylindrical gear pair of 3D mesh model. The dynamic response of the gear pair is analyzed using the Newmark- method under different meshing stiffness. The changes of spectrum are explained with different damping conditions based on modal analysis.Analysis result can provide powerful technical reference for the optimization design of the gear transmission system.
