摘 要: | 齿轮的振动能快速、全面地反映其运转状态,有限元法能更为准确模拟轮齿啮合过程,求解啮合刚度进而研究其振动响应。联合利用Hypermesh和Workbench对啮合齿轮模型进行有限元仿真,得出齿轮啮合时变刚度。利用MATLAB求解齿轮系统动力学模型得到动力学响应。通过机械式封闭功率流试验台对仿真结果进行试验验证。试验结果表明仿真分析得到的结果与试验结果基本相符。利用有限元方法求解啮合刚度进而研究振动响应有更高的可靠性和准确性,为齿轮振动的研究及改善提供方法参考。

Abstract: | The vibration of gear reflect its operating state quickly and comprehensively. The finite element method can be used to simulate the gear meshing process more accurately, and solve the meshing stiffness and study its vibration response. The finite element simulation of the meshing gear model is carried out by using Hypermesh and Workbench, and the time-varying meshing stiffness can be solved. The dynamic response of the gear meshing process is obtained by using MATLAB. Results of simulation agree well with those of experiments by mechanical test-bed of closed flow. The results of research turn out that the finite element method is reliable and accurate to solve the meshing stiffness and the result can be used to study the dynamic response, and the method is provided for the research and improvement of the gear vibration. |
