通过道路试验的方法针对四轮轮毂电机驱动电动微型车车内噪声问题进行振源、传递途径以及主要贡献板件识别.分析中分别加速工况、回馈制动工况和匀速行驶工况下车内噪声和结构振动信号进行测量,通过对试验数据时间域、频率域、阶次跟踪分析发现:轮毂电机引起的6阶振动是车身结构振动和车内噪声的振源;不同频率范围内车身各结构板件对车内噪声有不同的影响并进行了相关的分析.试验结果对轮毂电机驱动电动车的进一步开发具有参考价值.

Identification of vibration source,transfer way and main contribution panels are conducted consider-ing the interior noise of four--wheel-hub motor driven vehicle based on road test.Measurement of interior noise and vibration signal is conducted in accelera-ting,regenerative braking and constant speed driving conditions.Combining time domain,frequency do-main and order spectral analysis,and the result shows that the major source of interior noise is the sixth harmonic vibration of wheel-hub motor.The in-fluence of every body panel in different frequency range is also presented,which has reference value for the development of wheel-hub motor driven electric vehicle.
