Virtual simulation experiments can provide teachers with more teaching resources and methods,help them better organize and implement teaching activities,and improve students'learning effectiveness and participation.Based on its rich and diverse teaching resources and flexible teaching methods,virtual simulation experiments play an increasingly important role in current teaching activities.This article takes the curriculum reform of the discipline of ship and marine engineering structure design as the background,and elaborates in detail on the construction process of a virtual simulation experimental platform combined with engineering cases and its application in teaching.The virtual simulation experiment of marine engineering structures established in this article can help students gain a deeper understanding of the design methods and processes of ships and marine engineering structures,and improve their practical engineering design and analysis abilities.
