Abstract:

The integration of multi-disciplinary collaborative modeling and simulation is one of the key technical problems in the virtual prototyping design. Using CAD/CAE tools, the multi-disciplinary virtual prototype of space rendezvous structural latches is established, which involves structure strength, dynamics and effects of space environments etc. On the basis of collaborative design and analysis and collaborative modeling and simulation, reliability based multi-disciplinary design and optimization is carried out. Integration technologies in collaborative modeling and simulation, such as data integration and process integration, are researched in detail. This approach succeeds in finding the weak spots in design, and optimizes the reliability of space structural latches. Finally, general methods and scheme of reliability based multi-disciplinary design and optimization are presented and researched in complex mechatronics system, and a software platform(ARAMS)for reliability analysis is developed, which combines probabilistic analysis algorithms with general-purpose analysis packages(PROE, MSC. PATRAN, NASTRAN, ADAMS, ANSYS) to compute the probabilistic response and the reliability of engineering structures and mechatronics.
