瞬态响应计算中主控参数对响应影响的分析

以冲击载荷作用下的悬臂平板为例，分析了非线性瞬态响应计算的响应计算中时间长，重新形成刚阵与平衡迭代的时间步数，收敛误差及平衡迭代交数限等五个主要控制参数对响应计算的稳定性，计算精度和时间的影响，计算使用ＡＤＩＮＡ程序，结果表明；在重新形成刚阵及平衡迭代的时间步数小于３的条件下，可得到满意、稳定的计算结果。

Analysis of the Influence of Main Control Parameters in the Transient Response Calculation

or a cantilever plate subject to the impact loads,the paper presents the influence of a number of main control parameters on the calculating precision,the calculating efficiency and stability in the transient responces calculation. These parameters include the time increment,the convergent errors,the limitation of the iterative times and so on. All examples were computed by ADINA program. The results of the examples show that when the time steps in the reform of the stiffness matrix and the equilibrium iteration are within two steps,it is possible to obtain the stable and satisfactory numerical results.
