摘要
为了使数值解的最大响应谱不失真,讨论了数值求解微分方程的 Runge-Kutta法的积分步长、积分区间与响应谱自变量增量之间应满足 的关系。
Numerical solution of shock response spectra for vibration system based on Matlab is obtained under rectangular, forward & back peak saw tooth pulses. In order to acquire high accuracy of numerical solution, the paper discusses the relation satisfied between Runge-Kutta's integral time step, integral time interval and response spectra's variable increments.
