应用闭链机构公约束模型扩充自由度计算教学研究

Research on Application of Common Constraint Model of Closed Chain Mechanism to Expanding the Degree of Freedom in Calculation Teaching

机构自由度是"机械原理"教学中一个最重要的概念,是认识任何创新机构的前提和基础。针对目前机械相关专业"机械原理"教学中存在的机构自由度讲授思路单一性问题,以培养学生创新思维为目标,启发学生从多维度理解机构自由度概念,本文在原有的机构自由度讲授思路基础上,提出辅以单个独立闭链机构具有3个公约束模型的自由度教学新思路,为面向"一带一路"培养我国新时代具有创新思维人才提供教学模式借鉴。

Mechanism freedom plays an important role in Theory of Machines and Mechanisms,and is the first thing that should be known in further study of any other innovative mechanisms. In view of the monotony in the teaching classes the paper,with the purpose to cultivate students’ innovative thinking,aims at enlightening colleges and universities students to understand the conception of mechanism freedom. Based on the original teaching thoughts of mechanism freedom,the paper proposes a new thought of an auxiliary closed chain mechanism with three common constraints models,which provides reference for teaching patterns that cultivate innovated talents under the Belt and Road Initiative in new era.
