应用平均雷诺方程和粗糙表面弹性接触模型,建立了湿式离合器接合过程动态传递转矩模型。在湿式离合器接合过程动态传递转矩模型的基础上,建立了车辆起步过程中湿式双离合器联合起步动力学模型,并利用Matlab/Simulink仿真平台对模型进行了仿真验证。以20%油门开度起步为例,分别对引入动态传递转矩模型和经典静态转矩模型的湿式双离合器联合起步过程进行了仿真分析,结果表明,引入湿式离合器动态传递转矩模型能够更加真实地表征湿式DCT起步过程中转速、冲击度及滑摩功变化规律。
According to the engagement characteristics of wet clutch, average Reynolds equation and elastic contact model of two rough surfaces are applied to establish a dynamic transfer torque model for wet clutch engagement. Dynamics model of joint start for wet dual clutch is established based on the dynamic transfer torque model of wet clutch engagement in vehicle start, and the model is simulated and validated in Matlab/Simulink platform. Taking the startup with 20% throttle opening as example, two joint start process of wet dual clutch are analyzed and compared respectively on the basis of the dynamic and static transfer torque model. Results show that the simulation based on dynamic transfer torque model can more actually characterize the changes of rotation rate, jerk and friction work in the start process of wet DCT.
