| VRML is a totally virtual reality language for describing three-dimensional space.It has the function of timely rendering the model and the scene and also include the interactive operating,which can provide rich and colorful effect of modeling and scene,and the browser can have the feeling of being personally on the scene.In order to overcome the drawback of Planar projection view,which only relies on the establishment of three-dimensional space,and has the Poor graphics visualization.Based on the issues of developing new product of electro-hydraulic servo steering regulator,and With electro-hydraulic servo steering regulator for the prototype,using VRML virtual reality technology,this paper mainly research on the mechanical structure of 3D visualization technology.By analyzing and comparing,The study establishes the 3D visualization of specific methods and means of the electro-hydraulic servo regulator.combining of the 3DS MAX,Pro/E software and JavaScript language,and through the compatible interface,regulator in VRML 3D model of precision is established.According to analysis and calculation movement and moving relations of key parts and components of regulator,the action relationships between parts is identified.And it laid the theoretical foundation for simulating the real test environment and achieving regulator virtual reality system.Using the mutual acting relationships between parts of regulator,its virtual assembly,demolition and virtual scene interactive animation path is confirmed.Also the Association between nodes of sensor and interpolation for transmission and routing under VRML environment is established.Using the embedded access between the Java script scripts and the VRML which is perfectly matched,under the control and correspond of routing and transferring the links of Java script scripts,all interactive action appeared in virtual scene is come true.And it makes a powerful animation effects for the electro-hydraulic servo regulator virtual scene.This paper seeks to find a way to achieve a low cost desktop virtual reality system.Through the experience of virtual system produced in this paper,we can become familiar with and master the internal structure of electro-hydraulic servo regulator and its special place and movement relations,which can provide a practical value for the person who are familiar with the electro-hydraulic servo steering regulator design,operation and maintenance. |
