| Abstract: | The multi computer distributed optimization strategy and its related system architecture are proposed to achieve the optimizing integration of complex mechanical structure across the generalized optimization platform and FEA platform. Some critical techniques of structural integrated optimization are studied in detail, including automatic applying loads and boundary conditions along with automatic remeshing in FEA pre processing; data communication; remote control techniques etc. The strategy and techniques have been realized in conjunction with the generalized optimization modeling of hydraulic excavator. The optimization result and efficiency are satisfactory. |
