Abstract: This paper presents the network model of vibration of more general mechanical system. The efficacious algorithm of getting main way of vibration transfer----maximal flow diected way algorithm is given. By using the algorithm, the information (such as main way, secondary way) of vibration transfer of multi-input mechanical system can be obtained. In this paper, vibration network model of truck is analysed.
