基于MATLAB的机械振动分析

摘要

In most cases, mechanical vibration is harmful. Mechanical vibration, especially in the case of resonance, will affect the performance of the machinery and equipment. Therefore it should be controlled. MATLAB software is powerful in analysis. It can analyse vibration well so that to solve practical problems. The paper, making use of MATLAB, carries out a detailed analysis on two degrees of freedom vibration system by changing the parameters to research the movement. So vibration can be understood better, and a theoretical reference will be supplied for the actual production.%大多数情况下机械振动是有害的。机械振动特别是在共振情况下，可使机器和仪器的功能受到影响，结构和构件损坏或产生变形，因此必须进行有效的控制。利用MATLAB软件强大的计算分析功能，可以较好地分析振动情况，解决实际问题。本文利用MATLAB软件对两自由度系统的振动进行了详细分析，通过改变参量的数值研究其运动规律，从而更好地理解振动特点，为实际生产提供理论参考。
