摘　　要：复合行星排结构广泛应用于深度混合动力变速箱作为功率分流装置来耦合电机与内燃机动力。但由于复合行星排结构复杂,更多的齿轮啮合对数,更高的电机输入转速,伴随而来的是更复杂与严重的齿轮啸叫问题。针对某深度混合动力变速箱齿轮啸叫噪声问题,通过整车在最恶劣的工况下测试数据分析及主观评价,识别了对齿轮啸叫噪声贡献最大的激励源,得到了优化噪声目标值,通过齿轮接触斑点试验验证仿真模型的有效性,对齿轮进行微观修形,优化齿轮振动及啸叫噪声品质,使齿轮啸叫声压降至目标值。The compound planetary gear sets are widely used in full hybrid transmissions and taken as power-split devices to couple powers of motor and internal combustion engine. However,their complex structures have more gear meshing pairs and higher input rotating speed of motor,more complicated and serious gear whine problems come with them. Here,aiming at the gear whine noise problem of a certain full hybrid transmission,the excitation source making the maximum contribution to the gear whine noise was identified and the optimal noise target value was obtained through the whole vehicle’s measurement data analysis and subjective evaluation under the worst working condition. Then,the gear contact spot test verified the effectiveness of the simulation model. Finally,gears were micro-modified to optimize gear vibrations and gear whine noise quality,and make the gear whine pressure drop to the target value.
