摘要

为了方便求取力学系统模型的传递函数，将力学模型中的阻尼元件与质量块等效成复域内的弹性元件，提出了一个与电网络系统中复阻抗相似的复弹性刚度的新概念。将力学模型中的不同元件模拟成一系列串、并联的弹性元件，用同一概念处理遵循不同物理学定律的元件。避免了在求力学模型系统传递函数的微分方程的列写，而直接画出系统的方块图或信号流图。通过典型力学模型实例说明这一解决问题方法的正确性、简捷性

Abstract

There are many bumping and mass elements in mechanics model. In order to easily work out the transfer function of mechanics system model

we can take these elements as elastic elements in imaginary domain. A new coneept called imaginary elastic rigidity is introdnced. It is similar to imaginary resistance in electric metwork systems. Different kinds of elements can be seen as elastic elements in parallel or in series and can be handled with the same concept while in accordance with relevent physical laws. This method eliminates the necessity of differential equations to get transfer functions. We can conveniently and directly obtain the block diagrams of systems. This method is useful and simple. 
