## BUILDING THE LINK BETWEEN BASIC MECHANICS AND PRACTICE BY OPEN EXPERIMENT—STRESS ANALYSIS OF THIN-WALLED CYLINDER AS AN EXAMPLE1)

• 摘要: 以材料力学中典型的薄壁圆筒应力分析为例,设计了趣味开放实验。基于材料力学和弹性力学基础知识,将该例题结合易拉罐和储气罐等类似结构阐述薄壁圆筒的应力分布,通过理论分析、拉压实验和电测法实验探究了薄壁圆筒的内压和强度,实验结果与理论分析吻合较好。开放实验达成度表明,本项实验具有一定的趣味性和专业性,学生态度积极,综合应用能力有所提高,但也暴露了一些问题,为后续进一步改进开放实验举措提供了有力参考。

Abstract: Taking the stress analysis of a thin-walled cylinder as an example, an open experiment is designed. Based on the knowledge of materials and elasticity mechanics, the stress analysis of the thin-walled cylinder is described to model similar structures such as pop-up can and gas tank. The internal pressure and strength of the thin-walled cylinder are analyzed through theoretical analysis, tension experiment and electrical measurement experiment. The experimental results are in good agreement with those of theoretical analysis. The achievement degree of open experiment shows that this experiment has a certain interest and professionalism. Students have a positive attitude and recognize that the comprehensive application ability has been improved. However, this research also reveals some problems in this experiment. It provides a powerful reference for the further improvement of the open experiment.
