Instant Derivation of Transfer Function in Mechanics System Model

在把力学系统模型中的阻尼元件及质量块等效为弹性元件的基础上 ,提供了一种不经列写微分方程而直接画出系统的方块图或信号流图 。

On the base of taking bumping nd mass elements as equivlent elastic elements in mechanics system model,a useful and simple method is offered in this paper.This method eliminates the necessity of differential equations to get transfer functions.We can conveniently and directly give out the block diagram,and then derivate instantly transfer function of system.
