The exponential matrix function exhibition series was applied to solve the static problem; adopt the state space iterative method was applied to solve dynamic problem.
对静力问题,将指数矩阵函数展成级数来求解;对动力问题,采用状态空间迭代法来求解。
The procedure for calculating the exponential matrix guarantees that the simulation accuracy is not restricted by the calculating step length, then the calculating efficiency has been raised greatly.
