线性振动系统在脉冲激励下的响应求解，目前广泛采用的方法有卷积积分、拉普拉斯变换和数值方积分步长、积分区间的选取与响应谱自变量(BP频率fn与脉冲作用时间fn的乘积)增量的选取应满足什么关系，才能获得不失真的最大响应谱数值解是值得给予研究的问题。本文除以上问题进行探讨外。还试图借助Matlab软件在求解该类问题通用化方面做些工作。

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...
