摘要

在长弧形弹簧双质量飞轮结构的基础上，针对其核心部件——减振弹性结构形式进行创新设计，使得减振器的刚度由单级刚度变成了三级刚度。讨论了多级非线性双质量飞轮的各个参数的选取原则。针对国产某轿车的动力传动系统建立了离散化的整车动力传动系分析模型。对传动系统在行驶工况下和怠速工况下的固有特性进行分析，预测和评价多级非线性双质量飞轮的扭振控制效果。最后基于ADAMS对多级双质量飞轮的减振性能进行仿真和优化分析，得到了设计所需参数的最优值。

Abstract

Based on the structure of dual-mass flywheel(DMF) arc spring, design an innovation damping spring structure and makes stiffness of DMF from single-class to multistage. Established parameter selection principle and design process of multistage DMF,and also established a discrete model of a domestic car,evaluated the multistage nonlinear DMF torsional vibration control in the transmission and idling conditions. Simulated the multistage DMF damping properties by ADAMS. Finally optimized the design parameters.
