摘要： 受长弧形螺旋弹簧式双质量飞轮（DMF-CS）结构的启发，提出一种新型的扭振减振器 — 三质量飞轮，简称TMF。针对某车的传动系扭振问题，讨论TMF中阻尼系数、扭转刚度以及转动惯量的确定方法，得到和该车相匹配的TMF中各参数的取值方案，比较在此方案下TMF和原车所装配的DMF-CS的减振性能，并分析TMF对轴系安全性的影响。结果表明TMF在减振性能及轴系安全性方面皆优于DMF-CS，这也证明所采用的参数匹配方法的有效性。此外，还讨论TMF实现的可行性。

Abstract: Inspired by the structure of curved-spring double-mass-flywheel (DMF-CS), a new type of torsional damper, triple mass flywheel (TMF) damper, is introduced. As to the powertrain torsional vibration problem of a truck, the matching method for TMF’s parameters, including damping coefficient, torsional stiffness and rotational inertia, is discussed. And these parameters of the truck are obtained using this method. Based on these parameters, the damping performance of the TMF is compared with that of DMF-CS of the truck. The impact of TMF on the safety of the shaft system is analyzed. The results verify the effectiveness of the parameter matching method and show that the TMF has obvious superiority over DMF-CS in the aspects of vibration damping and shaft-system safety. Finally, the feasibility of TMF is discussed.
