| 摘 要： | 文中提出了一种基础加速度激励的数值仿真方法。该法通过引入基础激励影响系数向量,将基础加速度激励等效成系统的惯性力,克服了对加速度冲击先积分位移冲击再进行仿真的两点不足,可以直接计算得到系统的相对位移。文中给出了该法的理论基础,并用算例表明该法是合理、可信的。

| Abstract: | A new idea to access the simulation of a shock from the base was introduced.By using the vector called effective coefficient,the equivalent inertia force was obtained and then the system's relative displacement response versus time was computed directly.At the same time both the disadvantages of the method which used the displacement curve as the shock were overcomed.In this paper,the theory base of this method is presented,and its feasibility and reasonablity was shown by an example. |
