摘　　要：为优化某电动汽车的振动噪声性能,该文着重分析用阻尼复合材料代替电驱总成原有的ADC12材料控制器盖板的可行性和有效性。试验研究表明,更换阻尼复合材料盖板后,该电动汽车车内22阶噪声在部分频率段降低3 dB(A)左右,48阶噪声在部分频率段降低10 dB(A)左右。因此,选用新型复合材料来降低新能源汽车的振动噪声是一种有效措施。In order to optimize the vibration and noise performance of an electric vehicle,this paper focuses on the feasibility and effectiveness of replacing the original ADC12 material controller cover plate of the electric drive assembly.The experimental study shows that after the replacement of the damping composite cover plate,the noise of order 22 is reduced by about 3 dB(A)in the partial frequency segment,and the noise of order 48 decreases by about 10 dB(A)in the partial frequency segments.Therefore,it is an effective measure to choose new composite materials to reduce the vibration and noise of new energy vehicles.
