The support base is an important structure for the stable operation of the plasma cutting dust removal device. In order to enhance operation stability this device, this paper makes a structural optimization analysis of the support base based on the ANSYS Workbench software, including sensitivity analysis for design parameter of each structure, and identified 3 factors which have the greatest influence on the stable operation of support base, namely upper wall thickness, support wall thickness and support height. A second-order mathematical response surface model is constructed based on the experimental design methods, and iterative optimization is made through multi-objective genetic algorithm. The simulation results show that the natural frequency of the bearing increases by 20.47% and the maximum stress concentration decreases by 6.57%. The optimal Pareto solution of the parameter variables is achieved within the design requirements and the durability of the beam is significantly improved, which meets the optimization requirements.
