Sažetak
Optimization design for SHPS is investigated in this paper. Through finite element analysis, SHPS with torsional load on the upper beam and base together is determined as the optimization object. The distance between the cross-section of the live column and the top end of the outer cylinder of the adjustment jack P1, the horizontal distance between axis of lug and rear linkage P2, and the angle P3 of the inclined ramp are chosen as the variable quantity, and the maximum von-Mises stress and maximum total deformation are chosen as evaluation indexes, the size range of each variable is defined in ANSYS WORKBENCH (AW). AW implements force analysis and Solidworks reconstructs the optimization object within the variable range. Two pieces of software jointly implement the continuous modeling and simulation automatically to achieve the 3 factors and 2 levels central composite design experiment of the optimization object. The simulation results after each model reconstruction are recorded in AW. The effects of three selected variables on evaluation indexes are studied and the optimum structure of SHPS is determined. Compared with the original design, the two evaluation indexes decreased by 2,37% and 2,40% respectively, which improves the supporting ability of SHPS efficiently.
