凸轮机构及其动态特性虚拟仿真实验设计

Research on the Design of Virtual Simulation Experiment for Cam Mechanism and Its Dynamic Characteristics

采用仿真和虚拟现实技术,搭建“教学模式+分析模式+设计模式”3种不同阶段、不同深度、不同要求的学习层次功能模块,将抽象的凸轮机构及其动态特性课程理论教学内容进行虚拟实验场景开发与呈现,实现抽象理论知识点的工程化、形象化、可视化以及交互性虚拟实验功能。动态特性虚拟实验结果与理论计算结果高度一致,达到了虚拟实验研究预期目标。

An experiment adopted simulation and virtual reality is establishedfocam mechanism.Three types of learning function modules which have different stages, depths and requirements of teaching, analysis and design mode are designed. The abstract theory teaching of cam mechanism and its dynamic characters are developed and presented by virtual experiment method. And the student can get the theory knowledge by the virtual functions of engineering, visualization, imagination and interaction. The result shows that the virtual experiment meets the theoretical calculation well and reaches the expected target of virtual experiment research.
