复合行星齿轮系动态特性仿真分析
Simulation of dynamic characteristics of compound planetary gear trains
摘要
Abstract
In order to study the vibration spectrum of compound planetary gear train, a SD16 remanufacturing gear box was considered, and the dynamic model was established. Through the calculation and analysis of the speed characteristic, meshing frequency and meshing force of the system, the ideal meshing curve was proposed. By using ADAMS platform, the model was verified and the time domain and frequency domain characteristics of meshing force between sun gear and planet gear of the double row planetary gear in absolute coordinate were simulated to provide reference for the fault diagnosis of remanufactured gear box. The simulation results show that the waveform of meshing force in time domain can match up with the ideal meshing curve, which has notable volatility and periodic property. In the frequency domain, the frequency multiplication of 1 and 2 of meshing frequency are the main frequency, which have explicit amplitude modulating characteristic.关键词
