摘要
以某离心式压缩机齿轮-转子系统为研究对象,建立多平行齿轮轴ADAMS模型,从转速与啮合力两个方面验证了模型的有效性,并在考虑载荷以及偏差量的影响下针对轴线偏差故障进行了啮合力仿真分析。研究表明齿轮轴线平行度偏差对齿轮啮合力均值无明显影响,但引起其振动幅值的增大,加剧了非线性现象;负中心距偏差下啮合力振动幅值变大,正中心距偏差下啮合力振动幅值与载荷大小有关,但两种中心距偏差均没有引起啮合力频域成分和均值的明显变化。
Taking a centrifugal compressor gear-rotor system as the research object, a multi-parallel gear shaft ADAMS model is established, which is validated from two aspects： rotating speed and meshing force. The shaft deviation fault is simulated based on the ADAMS model considering load and the amount of deviation, The results show that shaft parallelism error has no effect on the moan value of the meshing force, but it increases the vibration amplitude significantly and intensified the nonlinear phenomena. Center distartce error has no effect on the mean value of the meshing force and frequency components, but the negative center distance error increases the meshing force vibration amplitude, the meshing force vibration amplitude under the positive center distance error depends on the load.
