Research Of Collaborative Assembly Based On VRML Model

At present the majority of the collaborative design system designers require in the same system in every part of the detailed design and assembly, and use of C / S structure. The obvious drawback of this system is large and complex, and safeguarding large amount of network hardware and transmission conditions requiring high, and low efficiency. To resolve these issues, this paper based on the B/S structure of the collaborative assembly system. This collaborative assembly system based on VRML model, system components required by the geographical distribution in the design of different experts in their own familiar with the CAD system design, good design into a CAD model to the system proposed in this paper for assembly.First of all this paper put forward a synchronous moving search algorithm. As different CAD modeling VRML import to be lost after the system parameters, such as the rotation axis model information will be lost for the resumption of the axis of rotation model information to the algorithm. The algorithm is suitable for any irregular rotation model. In the algorithm on the basis of proposed a VRML model of assembly algorithm. The algorithm in three parts, which is between three different parts assembly includes surface relative to the axis of consistency and consistency were analyzed. These algorithms from the fundamental solution to a VRML model for collaborative assembly on the basis of the key issues, and the implementation of speed, and high efficiency.Secondly design collaborative assembly system which based on the VRML model, the system uses B / S structure, the introduction of the traditional structure of MVC network design ideas. VRML is a combination of the interactive functionality and system advantages and events in the MVC structure in the network edge and in-depth study of the current browser with a VRML plug-in the realization of the shortcomings of the system. And on the basis of VRML expansion and optimization, and to enable it to meet the requirements of collaborative assembly.Finally in front of the algorithm and system model on the basis of a study on CAS-VRML system, which is based on the VRML collaborative assembly system. The system has the basic functions of collaborative assembly, a simple model can achieve synergies assembly operations. In this paper, and the synchronization of mobile search algorithm and collaborative assembly verification algorithm analysis, analysis of iterative step on the number of iterations and iterative errors, and VRML file in the network transmission efficiency were analyzed. Of the system to the traditional collaborative design system a significant improvement, which simplifies the complexity of the system, to increase work efficiency.
