摘　　要：针对当前高校实验室资源紧张,学生对实验机器、药品、细节和注意事项等缺乏足够认识等问题,本研究探究基于虚拟仿真技术的静电纺丝实验方案。使用3Ds Max进行纺丝机模型的搭建,并且创建机器组装动画,利用Unity游戏引擎搭建虚拟仿真系统,通过C#语言进行代码的编写,实现样品的制备以及纺丝的过程,充分展示实验的细节。本系统使用AABB包围盒碰撞检测算法与蚁群算法相结合的混合算法,将三维模型碰撞检测转化为二维离散空间中的优化问题求解,快速定位出碰撞点,较好地满足虚拟仿真系统的碰撞检测需求,较好地解决碰撞发生时模型穿透问题。In response to the current shortage of resources in university laboratories,as well as students’lack of sufficient understanding of the machines,chemicals,details,and precautions involved in experiments,the electrospinning experiment solution based on virtual simulation technology was explored in this study.The spinning machine model was constructed using 3Ds Max,and a machine assembly animation was created.Unity game engine was utilized to build the virtual simulation system,and C#language was used to write the code,enabling the preparation of samples and the process of electrospinning to be implemented.The experiment details were fully demonstrated.This system employed a hybrid algorithm that combines the AABB bounding box collision detection algorithm with the ant colony algorithm.It transformed the collision detection of 3D models into an optimization problem in a two-dimensional discrete space, rapidly identifying collision points and effectively meeting the collision detection requirements of the virtual simulation system, thereby resolving the issue of model penetration when collisions occur.
