摘　　要：针对ZA型汽车同步带,利用CATIA软件建立汽车同步带和带轮的三维模型,通过ANSYS软件进行了同步带的网格划分,并导入多体动力学软件RecurDyn,通过MFBD(多柔性体动力学)刚柔耦合技术建立了汽车同步带啮合传动的动力学仿真模型,对同步带带齿所受的齿面接触力和拉应力进行了传动性能仿真分析。给出了带齿与带轮啮合的带齿应力分布状态和带拉应力的分布状态,为汽车同步带齿形设计、传动性能分析和带的橡胶及强力层等材料的选择提供了一种数字化仿真分析设计方法。Aiming at the ZA type car synchronous belt,using the CATIA software,the synchronous belt and pulleys 3D model is created,synchronous belt mesh is divided with ANSYS software,and import into the multi-body dynamics software RecurDyn and the dynamics simulation model of the car synchronous belt transmission is built through the MFBD（multi-flexible body dynamics） techniques.The transmission performance of the synchronous belt,contact stress of tooth surface and tension stress is analyzed.The stress distribution between belt and pulley,and the distribution state of the tensile stress are given.A digital simulation and design method to design the car synchronous belt tooth shape,analysis of the transmission performance and select the material of rubber and the reinforcing cords are provided.
