有限元二次开发在大创项目及教学中的应用实践

Practical application of second development of finite element software in training program of innovation and entrepreneurship for undergraduates and course teaching

大学生创新训练计划项目对于提升学生的专业能力、科研素养和创新思维具有重要作用。对笔者指导的大学生创新训练计划项目的选题、内容和实施情况进行了详细介绍,并对存在的问题进行了讨论,提出了有益的建议。项目对通用有限元软件进行二次开发,将“钢结构设计原理课程”中的关键知识点做成典型案例模块,形成可视化交互式的虚拟仿真学习平台。在该平台上,学生通过亲自操作和互动,能够直观了解各种典型和新型钢构件的受力性能、失稳破坏现象和影响因素,从而加深对相关概念的认识和理解。虚拟仿真平台在课程教学中的应用丰富了辅助教学手段,提升了学生的实践能力和学习兴趣,取得了很好的教学效果。

The training program of innovation and entrepreneurship for undergraduates(TPI&E)plays an important role in improving students’professional ability,scientific research accomplishment and innovative thinking.This paper gave a detailed introduction to the selection,content and implementation of the(TPI&E)conducted by the authors,and discussed the arisen problems and proposed some suggestions.By conducting secondary development of the finite element software,the key knowledge points in the course of steel structures were made into typical case modules,to form a visual interactive virtual simulation learning platform.On this platform,the students can intuitively understand the mechanical properties,instability and influence factors of typical and new steel members through personal operation and interaction,so as to deepen the knowledge and understanding of related concepts.As an assisted teaching approach,the application of virtual simulation platform in course teaching improves the students’practical ability and learning interest,achieving good teaching results.
