摘要
本文在严格、完整的基础上,利用矩阵范数理论研究了结构非线性动力分析中数值积分格式的稳定性问题,给出了判别单自由度非线性动力方程积分格式稳定性的一般数学准则。为了实际应用方便,文中还给出了一个简化判稳准则。
The problem of stability in the numerical integration schemes of nonlinear dynamic analysis of structures is discussed by using matrix and norm theory on a rigorous and complete basis in this paper. A 'general mathematical criterion on stability for the analysis of non-linear dynamic systems with single degree of freedom is presented. For simplicity and practical application, a simplified stability criterion is also given in this paper.
