摘要

针对轻载齿轮动态分析仿真中齿轮系统起步阶段经常出现的系统高频振荡问题,提出运用动力松弛理论消除齿轮系统仿真过程中因初始加载产生的系统振荡。首先,分析了对直齿圆柱齿轮系统进行预加载的动力松弛过程。其次,基于LS-DYNA平台提出动力松弛法在齿轮系统动态仿真中的关键技术。最后,通过与传统加载方式的仿真结果对比,验证了该方法用于齿轮系统动态仿真分析求解时的有效性和更好的收敛性。

Abstract

Aiming at the problem of system threshold of high- frequency oscillation often appear on gear system starting in the light load gear dynamic analysis simulation system,an method of eliminating the system oscillation caused by initial loading based on the dynamic relaxation is presented. Firstly,the gear system preloading dynamic relaxation process is analyzed. Furthermore,the key technology of dynamic relaxation method in the gear system dynamic simulation based on LS- DYNA platform is put forward. Finally,the effectiveness and better convergence of method for using in the in gear system dynamic simulation analysis are verified by comparing with the simulation results of traditional way of loading.
