The Research on Simulation Design Program of Two Degrees of Freedom Damping Mechanical Vibration System

采用Matlab对机械振动系统的进行分析,不但能直观地了解到系统的振动状况,而且还能快速地掌握到系统的振动现状,从而能够较快为系统进行检验与修改。首先从概述机械振动相关原理为立足点;然后对机械振动系统仿真程序设计进行探讨;最后重点论述了二自由度阻尼机械系统建模与仿真。通过使用Matlab软件来对机械振动系统步骤进行分析,又灵活运用此软件编写程序建模、仿真设计,由此获得振动系统的运动规律,为教学与科学研究提供参考。

Using Matlab to analyze the mechanical vibration system can not only intuitively understand the vibration status of the system,but also quickly grasp the vibration status of the system,so that the system can be inspected and modified quickly.In this paper,the principle of mechanical vibration is firstly summarized,and this is the foothold.Then the design of the mechanical vibration system simulation program is discussed.At the end of the paper,the modeling and simulation of the two-degree-of-freedom damping mechanical system are analyzed in detail.The paper analyzes the steps of the mechanical vibration system by using Matlab software,and then flexibly uses this software to model the program and simulate the design,thus obtaining the motion law of the vibration system.It has certain reference value and guiding significance for teaching and scientific research.
