而后，分别采用时域方法和谱分析方法，预报快艇在不规则波中的运动响应，进而确定总纵弯矩。
Then the motion responses in a random seaway are predicted in time and frequency domain, and the bending moment of boat's girder is further deduced.
目前，计算总纵极限弯矩的方法主要有三种，即非线性有限元法，理想结构单元法和逐步破坏分析法。
There are three main methods by far, nonlinear finite element method, idealized structural unit method and progressive collapse analysis method.
