摘要
研究了动力方程的一种直接积分法在贝刚度条件下的收敛性和稳定性。在负刚度条件下，该方法是收敛的和无条件稳定的，它不仅适于分析有阻尼系统的动力反应，而且还适于分析无阻尼系统的动力反应。
The convergence and the stability of an explicit method for direct integration of dynarmc equation are studied in this paper for model with negative-stiffness. In the case of negative-stiffness, the method is convergent and unconditionally stable. It is easy to apply the method to the analysis of dynamic responses of damped and undamped system.
