摘　　要：国内管路抗冲击研究主要采用有限元法,求解的精度很大程度上取决于网格划分的密度。文章将传递矩阵法应用到舰艇管路抗冲击分析中,建立了含有支管的空间复杂管路的传递矩阵。提出了多支座激励下管路系统加载方法,并利用所建立的传递矩阵对某舰船冷却水管路的冲击响应进行了数值求解。研究结果表明,传递矩阵法用于管路抗冲击研究是可行的,具有求解自由度少,计算精度高的优点。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 mul-tiple supports was brought forward, and the numerical solution concerning the impulse response of a cer-tain 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 de-gree of freedom and high computational accuracy.
