摘　　要：基于多体动力学软件RecurDyn平台,结合某款汽油发动机正时带传动系统的布局设计参数,建立了该正时带传动系统的多体动力学仿真模型。通过理论与仿真计算,分析了带轮与正时带的静态接触力误差产生的原因,研究了正时带张力与传动误差的变化规律,并通过频域分析,分析了啮合频率与激励频率的响应特性。研究结果表明,基于RecurDyn的正时带传动系统多体动力学仿真技术可以为正时带传动系统的动态特性分析与性能评估提供一种有效可靠的研究方法。Based on the multi-body dynamics software RecurDyn, combined with the layout design parameters of a gasoline engine timing belt drive system, the multi-body dynamics simulation model of the timing belt drive system is established. Through theoretical and simulation calculation, the causes of static contact force error between pulley and timing belt are analyzed, the variation law of tension and transmission error of timing belt is studied, and the response characteristics of meshing frequency and excitation frequency are analyzed through frequency domain analysis. The results show that the multi-body dynamics simulation technology based on RecurDyn can provide an effective and reliable research method for the dynamic characteristics analysis and performance evaluation of timing belt drive system.
