| 摘 要： | 基于某款电动汽车两挡自动变速器，以齿面载荷分布和齿轮传递误差为优化目标，对比分析齿轮微观修形对电动汽车两挡自动变速器振动噪声的影响.建立电机转子-变速器刚柔耦合动力学模型，以变速器轴承处的振动加速度为激励，计算变速器在额定工况下的近声场辐射噪声云图和辐射声功率.结果表明，齿轮修形后变速器辐射噪声得到较好抑制，对指导变速器的优化和降低变速器的振动具有参考意义.

| Abstract: | Taking tooth surface load distribution and gear transmission error as the optimization objectives, the effect of gear micro modification on the vibration and noise of two-speed automatic transmission system was analyzed and compared for electric vehicles. A Rigid-flexible coupling dynamic model was established for the rotor and transmission of the motor. Taking the vibration acceleration at the bearing of the transmission as the excitation, a near-field sound radiation cloud and radiated sound power of the transmission under rated operating conditions were calculated. The results show that the radiated noise of the gearbox after gear modification can be well suppressed, providing reference significance for the optimization of the transmission and reduction of the vibration and noise of the transmission. |
