MATLAB仿真在机械振动课堂教学中的应用

Numerical Simulation of Mechanical Vibration with MATLAB

在机械振动课程教学中,通常将其作为一个力学体系进行分析,由于机械振动形式和外部作用的多样性,给教学工作带来一定的难度.在本文中将机械振动作为一个系统,外界的作用看作是系统的激励,将系统在激励作用下的运动看作是系统对激励的响应,从全新的角度来研究机械振动.在本文中运用MATLAB模拟了两种性质的机械振动,通过形象直观的图形演示能够使学生从全新的角度深化对机械振动的认识,激发学生的学习兴趣,提高教学质量.

The mechanical vibration is usually analyzed as a mechanical system in the traditional teaching. It is difficult to teach because of the diversity of mechanical vibration forms and external effects. In this paper;the mechanical vibration is regarded as a system;the action of the outside is regarded as the excitation of the system;and the motion state of the system under the action of the outside is regarded as the response of the system to the excitation. In this paper;three kinds of mechanical vibration are simulated by using MATLAB;The vivid and straightforward graphical presentation can enhance students’ understanding of mechanical vibration from a higher level;stimulate students’ interests in learning;and improve the quality of teaching.
