摘要

摘要本研究对纯电动汽车双速自动变速器(2EAT)齿轮传动系统的噪声进行了分析和优化。首先，通过车辆噪声试验，利用阶次分析法确定各齿轮副的不良工况和噪声贡献;其次，建立了齿轮传动系统的动力学计算模型和仿真模型，确定了特定条件下主减速器齿轮副啮合不良是产生噪声的主要原因;最后，采用遗传算法结合权值法对齿轮进行修形。改齿后传动误差波动范围减小，齿面接触状况明显改善。

Noise analysis and optimization of the gear transmission system for two-speed automatic transmission of pure electric vehicles

Abstract. In this study, the noise of the gear transmission system for two-speed automatic transmission (2EAT) of pure electric vehicles was analyzed and optimized. Firstly, through vehicle noise tests, poor working conditions and noise contribution of each gear pair were determined with the order analysis method. Secondly, a dynamics calculation model and a simulation model of the gear transmission system were established and the poor meshing state of the main reducer gear pair under specific conditions was determined as the main cause of noise. Finally, a genetic algorithm combined the weight method was used for gear modification. After gear modifications, the fluctuation range of transmission error was reduced and the contact condition of the tooth surface was significantly improved.

期刊介绍： The journal Mechanical Sciences (MS) is an international forum for the dissemination of original contributions in the field of theoretical and applied mechanics. Its main ambition is to provide a platform for young researchers to build up a portfolio of high-quality peer-reviewed journal articles. To this end we employ an open-access publication model with moderate page charges, aiming for fast publication and great citation opportunities. A large board of reputable editors makes this possible. The journal will also publish special issues dealing with the current state of the art and future research directions in mechanical sciences. While in-depth research articles are preferred, review articles and short communications will also be considered. We intend and believe to provide a means of publication which complements established journals in the field.
