The Support Assembly Of Standard Parts Library Of Key Technologies And Realization

With the development of CAD technology, as the important design resource, the application of standard part libraries in design is becoming more and more popular. Commonly, standard parts is almost 60 percent of the product, so with the help of standard part library, efficiency of design can be well improved. But the traditional standard part libraries have several defects. Firstly, the traditional standard part libraries can not manage assembly models, which made the assembly model designer very inefficient. Secondly, for the reason that the traditional standard part libraries can only be used in single CAD platform, when customer wants to share part information, he must do much repeated work, which prevents efficient improvement. Thirdly, current standard part libraries can't support reuse of non-geometry information well. Fourthly, as a resource library, it has low integration capability with PDM system.In the light of the problems above, the paper advanced the achievement method of the standard part library which can be used in the different CAD platform and can manage assembly models, and studied the integration of standard part library and AVIDM. The system has been validated in the UG and Pro/E platform. Main research work and achievements are as follows:1. Aiming at the problem that standard part library can not exchange data with PDM system, the integration method of AVIDM system and the standard part library was studied. According to the method of data input and data output of AVIDM system, finished the data management of AVIDM system.2. In allusion to the defects that the current standard part library can not be used in the different CAD platform, the rule of parameter parallelism was summarized based on intensive research on the modeling trait of the different CAD platform. The modeling module of different CAD platform was accomplished.3. Considering the defect that the current standard parts library can't support assembly parts, based on analyzing the requirement of the customers and the modeling method of assembly models. According to the modeling characteristic of different CAD platform, achieved the use of assembly models, and validated it in the UG and Pro/E platform.
