This article elaborates the concept and meaning of virtual reality technology and virtual maintenance, discusses the virtual reality technology application in the process of equipment maintenance, and gives a brief introduction to virtual maintenance system, which use VC and vega software as a platform and set up by Multigen Creator and 3D MAX, quoted an cannon as an example.
Maintainability is an important design character of product. How to improve the product's maintainability at design stage can reduce or eliminate maintenance costs, reduce downtime, and improve safety. In this paper, a virtual reality based on information management system for product maintainability improvement during design process is developed. The system aims at providing a simulated environment...
According to the concept and characteristics of virtual assembly feature, reconstruction method of virtual assembly feature model is proposed. Using the secondary development tools provided by ProEngineer, namely, ToolKit, getting assembly information is implemented. Based on analysis about three kinds mapping methods between the geometric elements and triangulated patches, an complete information...
Virtual Reality technology is being widely used in various fields, especially in industry. it is widely used in practice for assembly simulation. However, the size of the data for simulation expands quickly along with the increase in components, which make it inconvenient for web publishing but can only be viewed locally. This paper proposes a approach to reduce the size of simulation file using lightweight...
Virtual reality technique is applied in the industry widely, while the application of virtual assembly is rare in agricultural equipment. In this paper, we state several characteristics and key technologies on virtual assembly and have developed the virtual assembly system based on OSG which is a rendering engine. Finally, we described application of virtual assembly technique based on virtual reality...
Most current virtual maintenance systems are independent of CAD systems and the results in modification, maintainability analysis and evaluation can not be shared by CAD systems automatically and directly, reducing design efficiency and making information silo. The approach integrating virtual reality function into CAD system is adopted to build product information model of virtual maintenance integrated...
This paper describes a study of data transformation from CAD systems to virtual assembly (VA) environment based on STEP intended for simulation the assembly and disassembly process. This includes two steps. First export CAD data as STEP format file. Then translate STEP file into VA environment built with WTK toolkit. The transformation is realized based on the analysis of the STEP neutral file which...
This paper presents an architecture to support fast prototyping of augmented reality systems, based on virtual reality. The architecture defines simulation services separated from other aspects of the system. These services support incremental evolution of simulated prototypes into nonsimulated systems. Focus is also placed on user interaction,through the definition of an interaction architecture...
The development of virtual assembly platform (VAP) is discussed. It is a virtual environment on PC for training system that allows training supervisors to create training instructions and allows trainees to learn assembly operations. The models and the planning methods of assembly sequence and path are described. The virtual assembly simulation scenic framework is set up, and the level of detail technology...
