| 摘 要： | 针对如何在增强现实(Augmented Reality, AR)的虚拟环境中体现物体运动仿真时运动学与动力学特性的问题, 设计了一套将AR技术与物体运动仿真集成, 通过模型建立、标记物注册、运动仿真交互控制、增强场景实时渲染等步骤设计物体AR运动仿真系统. 该系统由运动学仿真模块和动力学仿真模块组成. 运动学仿真模块的设计和实现以刚体绕定轴转动和平面四杆机构的几何运动为例, 通过移动标记物进行运动学仿真的交互控制. 动力学仿真模块的设计和实现以曲柄滑块机构惯性运动为例, 通过改变输入参数进行动力学仿真控制. 最后以机械类课程教学中平面四杆机构急回特性学习和曲柄滑块机构动力学方程求解为例进行实际应用. 结果表明, AR运动仿真系统提供了直观的高交互操作运动学与动力学仿真环境, 通过可视化能帮助学生理解相关的理论知识, 进而实现虚实融合的智慧化运动仿真教学.

| Abstract: | An Augmented Reality (AR)-based object motion simulation system was designed to figure out the kinematic and dynamic characteristics of a physical object in an AR virtual environment. By integrating AR technique with physical object motion simulation, the system can help in model establishment, marker registration, interactive control of motion simulation, and augmented real-time rendering of scenes. It consisted of a kinematic simulation module and a dynamic simulation module. For the design and realization of the former module, the rotation of rigid objects about fixed axes and the geometric motion of planar four-bar mechanisms were taken as examples, while the interactive control of kinematic simulation was implemented by changing the markers’ placement. For the design and realization of the dynamic simulation module, the inertial motion of slider-crank mechanisms was taken as an example, with the control of dynamic simulation implemented by adjusting the input parameters. Then, the modules were put into practice through a mechanics course case study on the quick-return characteristics of planar four-bar mechanisms, and by solving the dynamic equations of slider-crank mechanisms. The final results demonstrated that the AR motion simulation system can provide a highly visual and interactive kinematic as well as dynamic simulation environment, help students understand relevant theories visually, and realize the smart teaching on motion simulation by the fusion of virtual technologies and reality. |
