Abstract A driveline model with 6° of freedom is established, the detailed structure of a clutch with three stages nonlinear stiffness and damping is presented and modeled, and the model for a driveline with unloaded gears and the nonlinear clutch is proposed. Taking the angular acceleration amplitude of the input shaft for a transmission as an evaluation index, the influence of model parameters on the angular acceleration of the input shaft is studied. For reducing gear rattle of the unloaded meshed gears of a generic passenger car, the proposed clutch is prototyped and its torsional stiffness, damping and moment of inertia of clutch driven disc are optimized to reduce the rattle. Experiment validates the performances of the developed clutch and the proposed clutch model.

降低传动空载齿轮卡嗒声的三级刚度阻尼摩擦离合器建模与分析

摘要 建立了自由度为6°的传动系统模型，提出并建模了三级非线性刚度和阻尼离合器的详细结构，并提出了空载齿轮传动系统和非线性离合器的模型。以变​​速器输入轴角加速度幅值为评价指标，研究模型参数对输入轴角加速度的影响。为减少通用客车空载啮合齿轮的齿轮咔嗒声，对所提出的离合器进行了原型设计，并对离合器从动盘的扭转刚度、阻尼和转动惯量进行了优化，以减少咔嗒声。实验验证了开发的离合器和提出的离合器模型的性能。
