摘　　要：针对混动变速箱中齿轮啮合传动出现的振动噪声问题,以专业的系统分析软件MASTA为仿真平台,利用其中的微观修形模块,对某一混动变速箱中的齿轮进行优化分析。通过比较修形前后的齿轮传递误差和齿面接触应力云图等评价指标,验证了基于系统分析软件MASTA对于微观修形的有效性,为实际修形提供了可靠的理论依据。分析结果表明,齿轮微观修形后,传递误差明显减小,齿面接触应力云图有较大程度的改善,对减小齿轮的振动噪声问题有着积极的作用。最后,对变速箱的齿轮振动噪声进行了数据采集和对比分析,结果表明,齿轮副经过微观修形后,相应的箱体振动加速度和齿轮噪声都会有明显改善。The optimization analysis of gears in a hybrid transmission is carried out using the micro-modification module in the simulation platform of system analysis software MASTA,aiming at the vibration and noise problems of gear meshing in hybrid transmission.By comparing the transmission error between gears before and after modification and the contact stress nephogram of the tooth surface,the effectiveness of micro-modification based on system analysis software MASTA is verified,which provides a reliable theoretical basis for actual modification.The analysis results show that the transmission error of the gear is obviously reduced after micro-modification,and the contact stress nephogram of the tooth surface has been improved to a great extent,which plays an active role in reducing the vibration and noise of the gear.Finally,the data collection and comparative analysis of vibration and noise of gears in transmission are carried out.The results show that the corresponding box vibration acceleration and gear noise will be significantly improved after the micro-modification of the gear pair.
