Computer-aided generation of equations and structural diagrams for simulation of linear stationary mechanical dynamic systems

Abstract

There are reasonable to use computer with MATLAB/Simulink software for modeling of dynamic systems of machine mechanic components, using lumped-parameter systems of them. In order to build structural schematics (Simulink blocks) of these dynamic models, there is a lot of work. This paper is intended to analyze linearized stationary mechanical system, which may be a part of more complex (nonlinear, nonstationary) system. There are presented methodology to build such Simulink model in the paper. Here are given analytical expression of differential equations and transfer functions for Simulink as well as numerical values. Simulink model is built in such way, that it is easy to attach necessary transfer functions of nonlinear or/and nonstationary connections. Example of such model is provided.
