摘　　要：随着科技发展,虚拟现实技术作为高新技术之一,以其安全性、经济型、可交互性及构想性的特点开始应用于高校的实验教学。本文针对并条工序实验中存在安全隐患、设备投入费用高等问题,以FA320A型并条机为仿真对象,设计了一款基于Unity 3D的并条工序实验虚拟仿真系统。根据课程内容的需求,系统确立了并条机构认知、并条机传动系统认知和并条工序实验三个模块,三大模块层层递进,引导学生自主完成并条工序实验的学习过程。实验表明该系统消除了安全隐患,激发学生自主学习的积极性,增加了学生的实验机会,平均完成次数为2.46次;有助于深化学生对理论知识的理解,学生成绩可提高1个等级,第二次实验的时间明显缩短,提升了实验教学的效果。Virtual reality technology is referred to as VR technology.Virtual simulation experiments are based on VR technology,which simulate a real experimental environment in the computer.With the help of necessary simulation hardware and software,users can interact and communicate with objects in the virtual environment,thereby generating an immersive operating experience.In 2017,the Ministry of Education promulgated the"Notice on the Construction of National Virtual Simulation Experiment Teaching Project",witch clearly pointed out that it is necessary to integrate information technology into the college experimental teaching,actively promote the construction of the national virtual simulation experimental teaching project,and improve the quality and technical level of experimental teaching.The construction of virtual simulation laboratory can shift the teaching mode from being flat to being three-dimensional and from being professorial to being experiential and students can gain more direct learning experience.At present,an undiversified offline teaching model is still adopted in the drawing process experiment,which has a certain gap with the new teaching concept of combining information technology and experimental teaching.In order to promote the informationization of the drawing process experiment,we design a virtual simulation system of drawing process experiment based on Unity 3D with FA320A type drawing frame as the simulation object.First of all,we analyze the actual requirements of the drawing process experiment,including:being familiar with the role of the drawing frame mechanism and components,being familiar with the drive system of the drawing frame and the position and function of the drafting change gear,mastering the process flow of drawing production,and knowing the relevant knowledge of textile workshop design.Then,the overall framework of the system is designed according to the teaching requirements.Three experimental modules are established,namely,the cognitive module for the drawing frame mechanism,th
