摘　　要：为了对压力机及其传动系统的故障诊断进行研究,以JM21-160曲柄压力机的齿轮传动系统为研究对象,对齿轮传动系统的啮合频率在理论上进行了计算,得到其啮合频率为82.499 Hz,并对齿轮啮合理论中的调幅调频现象进行了分析。通过CREO和ADAMS分别对齿轮进行了建模和仿真,并且对JM21-160曲柄压力机进行了振动试验测试。通过理论、仿真和试验数据的对比,发现三者得到的齿轮啮合频率在数值上基本相等,进而对JM21-160曲柄压力机的齿轮传动系统啮合理论的调幅调频现象和仿真结果进行了验证,证明了理论方法的正确性和仿真的可靠性,为后续研究压力机故障诊断方法奠定了理论和仿真基础。In order to research the fault diagnosis of press and its transmission system,for the gear transmission system of crank press JM21-160,the meshing frequency of gear transmission system was theoretically calculated as 82.499 Hz,and the amplitude and frequency modulation phenomenon in the theory of gear meshing was analyzed.Then,the gear was modeled and simulated by CREO and ADAMS respectively,and the vibration test of crank press JM21-160 was carried out.By the contrast of theory,simulation and experimental data,the gear meshing frequencies obtained by the three were basically equal in values,and then the amplitude and frequency modulation phenomenon and the simulation result of gear transmission system meshing theory of crank press JM21-160 were verified.Thus,the correctness of theoretical method and the reliability of simulation were proved,which laid a theoretical and simulation basis for the follow-up research on the fault diagnosis method of press.
