| Abstract: | To address the violet vibration problems of one automobile, the vibration transfer characteristics of leaf spring system is analyzed. The vibration acceleration on both sides of mounting system of the moving automobile is measured on actual road, by the time-domain analysis, the frequency spectrum analysis, relative analysis and transfer characteristics analysis of vibration signal, the main factor that influencing the transfer characteristic of the leaf spring system is found. According to the results, opportune improvement of leaf spring system is finished; the transfer characteristic of the leaf spring system is improved markedly. |
