摘要：

针对纯电动汽车两挡自动变速器在工作过程中存在的振动和噪声问题，通过建立变速箱-电机转子刚柔耦合动力学模型，对变速器系统进行传递误差、齿面接触应力等分析和计算。根据纯电动汽车的常用工况及其特点，以齿轮修形参数为优化变量，传递误差为主要优化目标，综合考虑齿面载荷分布以及齿面接触应力，在多工况下对齿轮进行修形。结果表明修形后达到了优化齿面载荷分布、提高齿轮使用寿命、减小振动、降低噪声的目的，实现了齿轮多目标优化。研究结果对纯电动汽车变速器的开发有一定的借鉴作用。

Abstract:

Focusing on the problem of vibration and noise in the working process of two-speed automatic transmission for an electric vehicle, the transmission error and gear surface stress were simulated and analyzed by establishing the rigid-flexible coupling dynamics model of the gearbox-motor rotor. According to the common working conditions and characteristics of the pure electric vehicles, the gear modification parameters were taken as the optimization variables and the transmission error was taken as the main optimization goal. The gear modification was carried out under multiple working conditions by considering the tooth surface load distribution and the tooth surface contact stress. The results showed that after the modification, the goal of optimizing tooth surface load distribution, improving the gear life and reducing the vibration and noise was achieved. The research realizes the multi-objective optimization of gear and provides a reference for the development of pure electric vehicle transmissions.
Key words: electric vehicle    two-speed transmission    gear modification    transmission error    multi-objective optimization
