摘要/Abstract

摘要： 针对某型纯电动皮卡在能量回收滑行阶段出现的电驱桥传动系统振动噪声异常问题，文章基于 MASTA 软件构建了电驱桥斜齿轮传动系统的刚柔耦合动力学模型，分析了低、中、高三种能量回收滑行工况下的啮合性能。通过正交实验法优化齿面修形方案，并在实车条件下对优化前后的三种工况进行了振动噪声对比测试。结果表明，优化后三种工况下齿面接触压力最大值和传动误差峰值均有所降低，实车测试中三种能量回收阶段在抱怨转速区间范围内噪声幅值分别减少了 12、7、4 dB(A)，有效改善了该电驱桥传动系统的噪声、振动与声振粗糙度（NVH）性能。研究结果为电驱桥传动系统减振降噪设计提供了有效的工程参考。

Abstract: To address the issue of abnormal vibration and noise in the electric drive axle transmission system during energy regenerative coasting of a certain type of pure electric pickup truck, a rigidflexible coupled dynamic model of the electric drive axle helical gear transmission system is developed using MASTA software in this paper. The gear mesh characteristics of the system are analyzed under three energy regenerative coasting conditions: low, medium, and high intensity. An orthogonal experimental design method is employed to optimize the gear surface modification scheme. Subsequently, vehicle-level tests are conducted to compare the vibration and noise levels under the three conditions before and after optimization. The results show that, after optimization, the maximum contact pressure and the peak-to-peak transmission error are reduced across all three scenarios. Accordingly, within the whining speed range, the vehicle tests under three regenerative coasting conditions demonstrate reductions in noise amplitudes by 12, 7, 4 dB(A), respectively, indicating a significant improvement in the noise, vibration, harshness (NVH) performance of the electric drive axle transmission system. These findings provide valuable engineering insights for the vibration and noise reduction design of electric drive axle transmission systems.
