CONSTRUCTION OF VIRTUAL EXPERIMENT SIMULATION MODEL BANK FOR MATERIAL MECHANICS UNDER NEW ENGINEERING BACKGROUND

Aiming at the cultivation of top innovative talents in new engineering, the author built a virtual experiment simulation model bank for the course of material mechanics. Especially, we integrated the analysis and design of axially compressed stability of rocket shell, the impact-resistant design of variable-stiffness ski helmet for Olympic Winter Games and other engineering cases. An information-based hybrid learning field integrating problem guidance, interaction, experience and reflection was established, which improves the integration project of science and education of material mechanics. Based on the Python language, a series of parameterized scripts for modeling and finite element analysis of standard components and engineering examples were established in this bank, which can automatically implement and show the process of finite element analysis of strength, stiffness and stability for typical engineering structures. On this basis, this paper also proposed a multiple formative assessment system for the whole learning cycle to realize the diagnostic evaluation of students' learning status and ability under the new situation, so as to promote students to make a reasonable learning plan, carry out learning independently and maximize the actual teaching effect of virtual experiment technology. The teaching practice demonstrates that the proposed virtual experiment simulation model bank is helpful to to cultivate students' engineering innovative capacity, and to stimulate students' emotion of serving the country, which has been the important carrier of ideological, political courses for mechanics of materials.
