摘　　要：为了加深学生对静定薄壁结构力学分析方法的理解,让学生做到“知识-能力”相贯通,研制了静定薄壁结构教学实验装置,该装置结构紧凑,操作方便,并具有明确的工程背景。由学生根据电测法测量结构的应变,并与理论解进行比较,分析实验误差原因,来提高学生分析问题、解决问题和独立研究的能力。实践表明:静定薄壁结构实验与理论教学有机融合,有助于学生对综合分析和知识应用能力的培养。To deepen the understanding of the mechanical analysis methods of determinate thin-walled structures, and to enable students to master the “knowledge-ability” interlinkage, an experimental teaching device for determinate thin-walled structures has been developed. The experimental device is compact, convenient to operate, and has a clear engineering background. Students measure the strain of the structure using the electrical measurement method, compare with the theoretical solution, and analyze the experimental error. By doing this, the students’ abilities in terms of analyzing problems, solving problems, and conducting independent research will be significantly improved. Practice shows that the integration of determinate thin-walled structure experiment and theoretical teaching helps students cultivate comprehensive analysis and knowledge application abilities.
