Optimal Design of Carrying Auxiliary Fixtures in an Automobile Production Line Based on Static Analysis Method

In this paper, through the multi-objective optimization design theory, a mathematical model with the maximum structural strength and minimum mass as the objective function is established, and the multi-objective optimization mathematical model can be solved, which the thickness of the square tube in the side frame components and support components is reduced from 3mm to 1.5mm can get the non-inferior optimal solution. Through ANSYS, the static analysis of the structure under full load and stacking conditions is carried out. Under the conditions of satisfying the structural rigidity, strength and deformation, the optimized structure is proposed, and the optimized structure is simulated and verified. The simulation results show that the optimized auxiliary carrying structure can reduce the weight by 17 percent on the basis of satisfying the requirements of use, which can better achieve the design goal and achieve the purpose of lightweight design of the carrying auxiliary fixture structure. This has engineering application value for the improved design of the carrying auxiliary fixture structure, and also provides a design idea for the same type of mechanical structure problems.
