摘要
介绍了一种求解有阻尼体系振动方程的显式积分格式及其逐步求解的过程 ,并对其计算精度和稳定性进行了分析。该方法不但能同时求得体系的位移、速度和加速度反应 。
This paper introduces an explicit step by step integration formula for vibration equation of damped structural system. The stability and accuracy of this formula are also discussed. Displacement, velocity and acceleration response of structural system can be obtained by this formula simultaneously. Accuracy of acceleration response is improved and satisfied for engineering application.
