摘要
针对汽车发动机同步带正时系统,利用AVL-Excite Timing Drive进行正时系统运行一个周期时的动态仿真分析,研究带在松、紧边和各轮接触时载荷变化规律。结果表明,在惰轮和排气凸轮轴带轮跨距间带的动态张力和动态张力波动幅值最大;曲轴带轮上带齿受载最大,并对啮入端的带齿载荷的峰值机理进行了研究。在系统主要振源振动性能分析基础上,优化了系统参数,仿真表明主要振源振动得到减小,也减小了系统传动误差。
For the automobile engine timing belt system,by using the AVL-Excite Timing Drive to carry out a periodic dynamic simulation analysis. The variation law of the load when the loose and tight of belt contact with pulley is studied. The results show that dynamic tension and its fluctuation of the belt between the idler and the exhaust camshaft pulley are the largest. And the peak mechanism of the belt toot load is studied. Based on the analysis of the vibration performance of the main vibration source,the system parameters are optimized. The results show that the vibration of the main vibration source is reduced and the transmission error of is reduced.
