摘要

在研究了传递误差的计算优化和频谱特性基础上，利用系统传动误差频谱特性及其激励下强迫振动的频率特性，巧妙地将齿轮多自由度振动模型简化为双质量振动模型，得到了齿轮传动误差激励下齿轮振动的解析解；建立了齿轮系统的质量、刚度、传动误差频谱与齿轮振动频谱的函数关系，得到了齿轮振幅、轮齿振动作用力、对轴承与箱体的振动作用力等关键的振动评价参数；并分析了质量、刚度和传递误差频谱对振动的影响。这对电动车减变速器的NVH（振动、噪声、声振粗糙度）问题的分析与解决提供了明确、可靠的方法。

Abstract

Based on the calculation optimization and spectral characteristics of the transmission error， the gear MDOF vibration model is dexterously simplified to a dual-mass vibration model by utilizing the frequency spectrum characteristics of the system transmission error and the frequency characteristics of the forced vibration under excitation. An analytical solution for gear vibration under the excitation of gear transmission error is obtained. A function between the frequency spectrum of gear quality， stiffness and transmission error and the vibration frequency spectrum of gear is established. The key parameters of vibration evaluation， such as gear vibration amplitude， vibration force of tooth， vibration force on bearing and housing are obtained， and the effects of mass， stiffness and transmission error spectrum on vibration are analyzed， which provides a clear and reliable way to analyze and solve the NVH（Noise， Vibration， Harshness） problem of electric vehicle reducer.
