The shock analysis of domestic piping system has mainly adopted the finite element method and the solution precision depends to a high degree on the mesh density. In this paper, the transfer matrix method was applied to shock analysis of warship piping system. Transfer matrix of spatial complex piping system which includes pipe branch was established. The loading method of piping system motivated by multiple supports was brought forward, and the numerical solution concerning the impulse response of a certain vessel's cooling water pipeline was carried out. The results show that the application of transfer matrix methods in shock analysis of warship piping system is feasible, and has the advantages of less solving degree of freedom and high computational accuracy.
