| 摘 要： | 利用虚拟样机技术对1.5 MW风电变桨行星减速机进行运动学、动力学仿分析,并在此基础上对箱体进行有限元模态分析。用接触力模拟齿轮啮合力的方法得出了行星减速机3级内齿圈的动载荷时域、频域变化规律,并对第3级内齿圈进行动载荷齿面接触强度校核。研究结果表明:减速机传动比仿真结果与理论计算结果相差仅为0.01,验证了建模方法的正确性;该行星传动属于具有较高可靠度的行星传动;在额定工况下,箱体固有频率与各内齿圈内齿啮合频率相差较大,不会发生共振现象。

| Abstract: | 1.5 MW wind-power pitch planetary reducer was analyzed with kinematics,and dynamics simulation and the box were carried out based on the finite element modal.To simulate the gear meshing force by using contact force,the method obtains the dynamic load time domain,frequency domain variation of three planetary ring gear reducers,and the intensity of tooth contact dynamic load of the third stage ring gear was checked.The results show that the tolerance between the simulation results and theoretical calculation... |
