摘　　要：有限元方法是沟通专业理论知识与复杂工程实践之间的桥梁,通过有限元分析软件实践课程的学习,学生能够学会利用数值模拟方法解决一定的实际问题。针对该类软件应用课在传统教学中存在“重实践-轻理论”问题,本文以石油化工领域常见的输送管道为工程原型,将其由于焊缝缺陷下的应力集中问题作为课程案例,提出了“刨根问底”的教学思想。教师在课堂上除了引导学生熟练掌握软件操作外,还应当利用所学理论知识探究仿真算例中的理论机理,加深对相关工程问题背后所蕴含知识点的理解和掌握。此教学方法不仅能改善工程类专业实践课程的教学质量,还能培养学生的自主钻研精神和科学创新意识,是对现代化多元教学模式的积极探索。The finite element method is a bridge between professional theoretical knowledge and complex engineering practice.Through the study of finite element analysis software practical courses,students can learn to use numerical simulation methods to solve certain practical problems.In response to the problem of“emphasizing practice over theory”in the traditional teaching of finite element analysis software practice courses in colleges and universities,taking the common transportation pipeline in the petrochemical industry as the engineering prototype,and taking the stress concentration problem under weld defects as an example,a teaching philosophy of“digging into the root”is proposed to guide students to use their theoretical knowledge to explore the theoretical mechanisms in simulation examples and deepen their understanding and mastery of relevant knowledge,in addition to mastering software operations proficiently.Such method not only improves the teaching quality,but also cultivates the independent research spirit and scientific innovation consciousness of students,which is a positive exploration of modern diversified teaching models.
