摘　　要：“机械原理”课程是机械设计制造及其自动化专业的主干专业基础课,如何结合实际控制目标对“机械原理”课程教学进行创新改革值得深入思考。针对目前“机械原理”课程中涉及的机构,很难利用尺规作图法来快速得到任意机构中某一构件的运动学和动力学分析结果。为此,将基于MATLAB的计算机辅助编程融入“机械原理”课程教学中,让学生通过该部分的学习从理论上彻底了解并理解各机构的运动特点及其主要的设计思路。结果表明,参与教改班学生的知识体系在一定程度上得到了提升,成功实现了将基于MATLAB的计算机辅助编程融入“机械原理”课程教学改革中。为培养兼具机械结构设计、计算机编程技术及刚体动力学的复合型人才提供了强有力的支撑。Mechanical Principles is a fundamental course in the field of mechanical design,manufacturing,and automation.It is worth considering how to innovate and reform the teaching of mechanical principles based on practical control objectives.In view of the mechanism involved in the current mechanical principle course,it is difficult to quickly obtain the kinematics and dynamics analysis results of a component in any mechanism by using the ruler and gauge drawing method.To this end,MATLAB based computer-aided programming will be integrated into the teaching of mechanical principles courses,allowing students to thoroughly understand and understand the motion characteristics and main design ideas of each mechanism in theory through this part of learning.The results indicate that the knowledge system of students participating in the teaching reform class has been improved to a certain extent,and the integration of MATLAB based computer-aided programming into the teaching reform of mechanical principles courses has been successfully achieved.It provides strong support for cultivating composite talents who possess mechanical structure design,computer programming technology,and rigid body dynamics.
