[Abstract]:The transfer path analysis method is used to analyze the idle jitter of the steering wheel of a light bus by establishing a transfer path model. The theoretical derivation process of transfer path analysis and its application in practical problems are described. The transfer function and working load identification of each structure transfer path of engine mount and exhaust suspension are obtained and the contribution of each structure transfer path is obtained. By synthetically considering and analyzing the factors of amplitude and phase of the contribution, it is determined that the most outstanding contribution to idling wheel jitter is the X direction and Z direction which are mounted at the back of the engine, indicating the direction for the improvement of idling steering wheel jitter.
