Abstract
To realise the transfer of model from CAD system to virtual assembly system,an assembly information representation based on OpenFlight is proposed.The method divides the model information required by the virtual assembly into two levels,the information of assembly model and the information of the parts model.It extracts the information of these two levels by secondary development of CAD system,and writes them respectively to the expanded OpenFlight database.The complicated mapping mechanism in model reconstruction is solved by the OpenFlight-based information representation,and this avoids the writing process by the assembly information to an intermediate file.With the scalability,the method is a better solution for integrating the data between CAD system and virtual assembly system.A virtual assembly system based on Vega is established and the feasibility of transform method is verified.关键词
