摘要
介绍能量贡献率的概念与计算方法,计算分析某款大客车驱动桥引起的阶次噪声对总体噪声能量的贡献比例,然后设定车内噪声限值与改进目标,并评估其改进效果。
This paper introduces the concept and calculation method of energy contribution rate, calculats and analyzes the contribution rate of the drive axle order noise energy to the overall noise energy for a large coach, then sets the limit value and the improvement target of the vehicle interior noise, and evaluate the improvement effect.
