基于VRML的机械产品可视化装配及其应用

虚拟装配是虚拟现实技术在制造业中的一项重要应用，借助虚拟现实技术，在设计阶段就可以对产品进行虚拟装配。研究了网络制造环境下机械产品的可视化装配技术中动态VRML场景、虚拟装配控制、碰撞检测，提出了通过将虚拟模型运算交由服务器来完成的结构体系，解决传统虚拟装配中的碰撞检测技术的不足；并提出通过保存零件运动的关键点，对运动路径进行修改和控制的方法，减少了编写VRML程序的工作量。

Application of mechanical product visualization assemble based on VRML

Virtual Assemble is a key application of Virtual Reality Technology in Manufacture Industry.With the assistance of Virtual Reality Technology,Virtual Assemble can be carried out during design stage.Study on dynamic VRML scene,control of Virtual Assemble and Collision check-up of mechanical product visualization assemble technology in the environment of network manufacture is conducted.And then,a system handing operations of virtual product model to server is advanced,which solves the deficiency of traditional virtual assemble technology in collision check-up.In addition,a method through saving the key moving points of parts and then adjusting and controlling the moving path is put forward,which reduces the load of VRML programming.
