摘要
作为理论力学专题内容,机械振动体现了对运动学和动力学内容的综合运用。以计算机辅助教学的方式可强化学生对理论知识的理解,增强教学趣味性。介绍了利用MATLAB求解振动微分方程的方法,提出了在上机实践课中引入图形交互界面制作环节,让学生直观理解阻尼和激振力对振动的影响,并在界面制作与操作过程中提升学生对机械振动知识的兴趣,达到了虚拟仿真课程的教学效果。依托交互界面,帮助学生进一步探索隔振和减振的方法,增强学生发掘新规律、新方案的好奇心。
As a topic of theoretical mechanics,mechanical vibration embodies the comprehensive application of kinematics and dynamics.Computer-assisted teaching can strengthen students'understanding of theoretical knowledge,making the class attractive.This article introduces the method of using MATLAB to solve the differential equations of vibration,and proposes to introduce the graphical interactive interface production link in the computer practice class,so that students can intuitively understand the impact of damping and excitation force on the vibration effect.In the process of interface production and operation,students'interest in mechanical vibration knowledge can be enhanced,achieving the effect of virtual simulation course.The interactive interface can help students further explore the methods of vibration isolation and damping,and enhance the curiosity of students to discover new laws and new solutions.
