Abstract

In this paper, a dynamic simulation of synchronous belt drives of a kind of engine is discussed using AVL—EXCITE TD software. The dynamic characteristics of belt on all kinds of speeds are analyzed. The influencing factors to dynamic characteristics of synchronous belt drives are also analyzed and optimized. The results show that the reduction of the crankshaft speed fluctuations can improve the dynamic performance of synchronous belt drives effectively. They also provide the basis for the design of valve system and essential boundary conditions for the analysis of valve system, timing system and overall NVH performance.
