Optimization of 12Х18Н9Т-Steel Processing by Ring Laser Beams

Using the MOGA genetic algorithm built into DesignXplorer module of ANSYS Workbench program, optimization laser processing 12Х18Н9Т-steel by annular beams has been performed. The calculation temperature fields carried out taking account dependence thermophysical properties material on finite element method in program. A regression model obtained for using a face-centered variant central compositional plan experiment. power density and duration radiation pulses, outer inner diameters beam plane were used as variable factors. penetration depths maximum temperatures zone responses. influence parameters impact values evaluated. It established that depth are most affected radiation. Optimization was setting limiting tempe-rature three variants minimum depth. result modeling compared. relative error results when determining did not exceed 1 % 6 %.
