| 摘要： | The methods of mode and vibration transfer function(VTF)are utilized to investigate the abnormal vibration of the mid- dle seat. The modal frequency and VTF of the studied seat obtained using the finite element method are approximately consistent with the experimental results. The transfer path analysis(TPA)and the corresponding contribution show that the major path is X-direction of front suspension to Z-direction of seat mount, and final to X-direction of seat back. Based on the above method, a optimization scheme is proposed, and the experiment results show a apparent decrease in the vibration amplitude. |
