摘　　要：用传统与规范方法系统地分析波浪中船舶惯性力的计算,通过比较总结出两种方法的优缺点,传统方法较适合于手工粗略计算,而规范方法更适合于有限元分析平台上的复杂结构计算。同时对ANSYS结构分析中船舶惯性力的加载方法进行探讨,将传统方法和角加速度加载方法作对比,分析和实际计算得出两种方法计算结果基本一致,但角加速度加载方法更为简单直接,避免了许多繁琐的过程。The traditional and normative methods to calculate the ship＇s inertia forces in waves are compared. The traditional method is propitious to cursory analysis, and the normative one is more capable of exact calculation, especially in finite element analysis of structure. The authors also discuss about the method of applying the ship＇s in- ertia force on the structural model in ANSYS. The applying method by the angle acceleration is different from the traditional method, but it is accurate, direct and much simpler to use.
