Web-Based Research On Legs Of Truck Crane CAD System

With the rapid development of web technology, web-based CAD system has been gradually mature. Using Web-based cooperative design makes designer and enterprise broke geographic location restrict, achieved sharing and communion of information. For international web technology in developing condition of manufacturing and track crane of CAD system in applying condition of cooperative design, CAD technology is well combined with web technology in this paper. Under B/S/W pattern, this paper realizes web-based cooperative design by taking an example of track crane legs, and using ASP technology which based on SolidWorks.The characteristic of the paper is the second development of track crane legs by virtue of VB based on SolidWorks, it encapsulates the design programs of legs into a series of components, one of which has an interface for key references, so that the client can transfer them through ASP on the internet. If the client input the corresponding key references of any part, the server would answer the demanding immediately, transfer the component to draw by SolidWorks. Finally, the client would get a visual figure on his browser. Thus it realizes the web-based collaborative design of track crane legs.This paper integrates the technology of design on line, parameterized solid modeling, browse of web-based figures, and assembly design, setting electric white board and chat room etc. which can help the design quickly and efficiently. Finally, this paper takes an example of legs that is one main part of QY25B track crane, which verifies veracity and feasibility of the result.
