摘要
本文首先介绍了数值分析方法的基本思想 ,然后参照 Dunkerley's公式 ,提出了一种用于确定结构动力响应数值分析时间步长的方法。
This paper introduces basic considering of numerical method. Then according to Dunkerley's formula,suggests a method of ascertain integration's time marching about numeral method for calculating dynamic response of Vib system. In the end verifies the method's availability through example and gives some discussions about the results.
