摘　　要：文章以六西格玛设计作为工程分析方法,运用Simdrive 3D软件对某汽油发动机的附件皮带驱动系统性能进行了仿真分析,详细计算了各种控制因子组合成的系统中其张紧器摇臂的摆动量、驱动附件皮带轮的打滑率以及敏感段皮带的抖动量。通过对计算结果进行分析,找出最优的控制因子组合从而设计出性能最稳定的系统,该方法可以应用于发动机附件皮带驱动系统的早期开发阶段。Based on DFSS (Design for Six Sigma) methodology, the performance of engine front end accessory drive system is analyzed via Simdrive 3D software. The tensioner arm movement, the accessory pulleys slippage and the vibration amplitude of sensitive belt span in different groups which is combined with various control factors is calculated, and the results are analyzed by applying the systematical process and tools of DFSS to optimize control factors so as to design a robust system. This method can be applied in the initial period of the engine accessory belt drive system design.
