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.
