| 摘 要： | 介绍了精细积分法的基本原理及精细积分法的稳定性,通过给出的一个算例,比较了用精细积分法与中心差分法、Newmark法的计算结果。结果表明用精细积分法得到的位移响应最接近理论值,而且当取相同位数有效数字时,与理论值完全一致。

| Abstract: | After introducing the basic principle and stability on the precise integration method, the result of a simple example calculated by precise integration methed is compared with the results of the same example calculated by the central difference method and Newmark method in this paper and the numerical result shows that the displacement response obtained using precise integration method is closest to the theroretical value, especially using same digits for effective numbers, it is exactly same with the theroretical value. |
