摘要
对摩托车发动机壳体进行噪声测量和振动测试,将试验结果进行分析比较得到了壳体噪声的分布规律:最外层凸面和小圆处辐射噪声能量较强,其中最外层凸面中心处最强烈,辐射噪声大的区域振动也较强烈。据此,对壳体提出了相应的减振降噪措施,为摩托车发动机壳体的结构优化提供参考依据。
The noise measurement and vibration test is made on motorcycle engine shell, and the shell noise distribution is obtained through the analysis of experimental results： the radiated noise power of the outer convex and small circular is strong, in which the center of outer convex is the strongest, and the vibration of loud radiation noise area is intense. And the vibration and noise reduction measures corresponding to the shell is proposed, providing reference basis for the structure optimization of the motorcycle engine shell.
