摘要
基于Sysnoise对摩托车变速箱箱盖噪声进行了声学模拟,验证了声学模拟的正确性,分析了分别采用改变箱盖紧固螺栓位置和改变箱盖阻尼的方法对其NVH性能的影响。
Based on Sysnoise acoustic simulation of the noise operates for motorcycle gear box cover to verify the correctness of the acoustic simulation and makes an analysis of the effect of changing the position of the fastening bolt and the box cover damping on NVH performance.
