有阻尼多自由度系统载荷响应函数及其应用

本文开发线性系统的模态分析法,继作者建立的无阻尼多自由度系统载荷响应函数之后,进一步导出有阻尼多自由度系统的载荷响应函数,并将其应用于求解线性离散系统对任意线性外扰力的瞬态响应问题。根据本文导出的方法,编制了求解在初始条件下系统对线性外扰力的瞬态响应程序,并在PC-1501计算机上调试通过。本文导出的方法和程序已应用于4200厚板轧机主传功机构的动态响应计算,获得了满意的结果。

LOAD RESPONSE FUNCTION FOR DAMPED MULTI-DOF SYSTEM AND ITS APPLICATION

Following his establishment of the damping-free multi-DOF load response function, a. modal analysis for linear systems is developed herein this article. The author furthers his study to develop a response function for damped multi-DOF systems and applies it to solve problems concerning transient response for linear discrete systems acted on by arbitrary linear disturbing forces. A program to solve for the transient response to linear disturbing forces under assigned initial conditions is compiled in accordance with the method introduced in this article. The program has been successfully debugged and run on a PC-1501 computer. The is procedure and the pertinent program are in use for the computation of dynamic respose in the main drive on a 4200mm heavy plate mill with satisfactory results.
