Abstract
The presently developed computer-based design systems are not effective for design of complex mechanical products when multiple tools and methods in different schemes have to be employed at different design stages. In this research, a new integrated framework has been introduced for the design of complex mechanical products considering modeling, simulation/evaluation, and optimization aspects. An integrated system for design of complex mechanical products has also been developed. In this system, first a hybrid scheme is introduced for integrated modeling of complex mechanical products considering conceptual design and detailed design stages. In conceptual design, the generic product considering different design solution candidates is modeled in an AND-OR tree. Specific design candidates modeled by AND trees are created from the generic AND-OR tree through tree-based search. The geometric descriptions in a design candidate are then converted into and associated with the geometric model in a CAD system for detailed design. Second, a hybrid simulation method is developed for evaluating different product aspects with different simulation tools that are integrated through the hybrid modeling scheme. Simulations with geometric descriptions are conducted by analysis functions of the CAD system for detailed design. Simulations with non-geometric descriptions are conducted by the knowledge-based systems for conceptual design. Third, a hybrid optimization method is developed to identify the optimal design of the complex mechanical product. For each design candidate, parameter optimization is conducted to obtain the optimal parameter values. The optimal design solution is identified from all design candidates through configuration optimization. The integrated complex mechanical product design system has been implemented using C# and SOLIDWORKS. Various user interfaces were developed for conducting design activities in modeling, simulation/evaluation and optimization aspects. Communication between the symbolic model in conceptual design and the CAD model in detailed design was achieved through TCP/IP client-server structure and SOLIDWORKS API. A case study has been developed to demonstrate the effectiveness of the newly-introduced design approach.
