Abstract: To find and solve layout & assembly problems of the Complex Structure Product (CSP) in design stage, based on the CSP design characteristics, requirements of Virtual Layout and Assembly System for CSP (VLAS-CSP) were analyzed. In this system, the layout solution was achieved by constructing optimization algorithm and the assembly ability of product was tested and evaluated by virtual assembly technology. Function model of VLAS-CSP was constructed, and key technologies of system implementation including the solution algorithm for complex layout problems, product modeling oriented to virtual assembly and virtual assembly simulation were elaborated. Based on these principles and techniques, taking the apparatus cabin of flight vehicle as research object, a prototype system of VLASCSP was developed. Some primary verification job was performed in the prototype system. Result indicated the feasibility and practicability of proposed system principles and implementation techniques of VLASCSP.
