利用VRML实现行星轮系机构运动仿真

虚拟设计是CAD研究的重要内容，它在机构设计中得到广泛应用，现在许多CAD软件都可以对机构进行虚拟设计并进行运动仿真以验证其正确性．但其存在文件大、交互性差、不便于网上传输的缺点，VRML对解决该存在的问题提供了一种崭新的思路和方法．本文介绍了VRML语言特点，研究了利用CAD软件和VRML建立虚拟静态模型和动态模型的方法与原理，并以行星轮系机构为例重点阐述实现其运动仿真的关键技术．

Realization of Planetary Gear Mechanism Movement Simulation by VRML

Virtual Design is a very important aspect in CAD research and it is widely applied in the design of mechanism.Now many CAD softwares can realize the virtual design of mechanism and simulation of mechanism movement.But its file is bulky and the interaction is weak,so it is difficult to transfer on the web.VRML provides a brand-new thought or method to resolve the problem.The feature of VRML is introduced in this paper and the method and principle of creating static and dynastic virtual model using CAD softwa...
