摘要/Abstract

摘要：

通过建立单节弹簧单元受力模型,分析了长弧形螺旋弹簧在加载和卸载工况下的扭矩负载特性及影响因素。研究表明：弹簧在工作时处于非均匀压缩状态,具有非线性动态迟滞,且发动机转速及摩擦因数越大,迟滞效应越大。在此基础上,仿真计算了双质量飞轮与传统离合器从动盘式扭转减振器的动态响应,仿真结果表明:双质量飞轮可大幅度降低变速箱输入轴振动响应,从而降低传动系统的振动噪声。

Abstract:

In light of the working principle of DMF-CS(dural mass flywheel-circumferential spring), a force model of single-coil spring unit was established to analyze the loading and unloading torque characteristics of equations of the arc spring, as well as the influencing factors.Results reveal that the arc spring are compressed inhomogeneously in operation condition, and

possesses nonlinear hysteresis characteristics which is proportional to the engine speed and friction coefficient.On the basis of that,a comparison between DMF-CS and

CTD(clutch torsional damper) is simulated, which illustrates that the former can greatly attenuate the oscillations in automotive powertrains and to reduce the vibration response of gearbox input shaft.

Key words: arc spring, dynamic load characteristics, friction damping, hysteresis characteristics, simulation analysis
