| 中文摘要: |
| 利用钟万勰等发展的指数矩阵精细算法,提出了状态方程直接积分法。它能适用于确定情形各种激励作用下系统的动力响应分析;与分段等效线性化方法相结合,也可用于某些非线性系统的响应计算。算例表明,状态方程直接法具有精度高、不受时间步长的严格限制等特点。 |
| 英文摘要: |
| Based on the precise integration method, the Direct Integration of State Equation Method (DISEM) was developed to calculate the dynamic response of the system excited by deterministic forces. It can be used in kinds of systems. Combined with the piecewise linearization, it can be used to compute the response of some nonlinear system. Some numerical examples were given and the results show that the DISEM is in high agreement with the exact solution, and not be restricted with the time step. |
