摘　　要：针对BAS发动机附件系统复杂的工况,提出了减振皮带轮紧固系统的正向开发方法。结合CAE计算在设计前期得出前端附件系统的需求扭矩,通过计算设计了皮带轮固定螺栓规格与链轮的接触面特征,并利用CAE静态分析计算皮带轮受的弯矩对整个紧固系统的应力分布影响。后期通过皮带轮的滑移试验以验证紧固系统的安全性及计算的准确性。研究结果表明,理论计算的皮带轮打滑的扭矩与实测结果一致性好,该正向设计方法能有效地预测皮带轮紧固系统性能,规避其在开发阶段台架及整车试验的失效风险。Because of the complicated BAS system working conditions,this article raises up a new design method of the BAS filter fastening system.The interface maximum torque is obtained by CAE calculation,and an optimized bolt and sprocket are chosen for the engine.The bending influence of the Front End Accessory Drive(FEAD)system is also taken into consideration by static CAE calculation.The safety factor and the calculation are proved by the slip test at the end of the research,which shows a good consistence.This design method can effectively predict the performance of fastening system and avoid the risk of bench test and vehicle test failure.
