摘　　要：双质量飞轮对于动力输出的稳定性有较大的提升,可以有效提升整车的NVH性能,但是对于曲轴系统来说振动增大,对于前端轮系有一定的危害,而之前的分析主要针对单质量飞轮的扭振分析,对于双质量飞轮系统的分析目前还不是很成熟,本文基于EXCITE DESIGNER对双质量飞轮的曲轴系统进行建模。分析结果表明,此方法可以得到双质量飞轮曲轴系统的扭振,并且可以判断双质量飞轮是否会与发动机怠速工况发生共振。The double mass flywheel (DMF) can increase the stability of power outputting. And it can also improve the NVH performance of vehicle. But the vibration increases for crankshaft system. And it is bad for Front end accessory. The research before directs towards the single mass flywheel system. It is not proficient in analysis for DMF crankshaft system. This paper models the DMF system based on the software EXCITE DESIGNER. The results show that this method can calculate the torsional vibration of DMF crankshaft system. And forecast whether the DMF can resonate with the case of idle.
