【 摘 要 】

Dual mass flywheel (DMF) can effectively attenuate torsional vibration from the engine. Aiming to obtain greater damping performance, the sensitivity analysis method is studied combining with the constraint relation of primary flywheel assembly and secondary flywheel assembly, which is used to determine the key structural parameters of DMF which have the greatest relationship with the natural frequency of the system. A car with a DMF is taken as an object of sensitivity analysis, then the key structural parameters of the DMF is obtained and adjusted, finally, simulation results verify the effectiveness of the analysis method.
