Research on simulation and experimental synergistic analysis method for laser quenching temperature field of 45 steel

The processing effect of 45 steel laser quenching is affected by a variety of process parameters. In this paper, a simulation and experimental synergistic analysis method for laser quenching temperature field is proposed to accurately predict the laser quenching temperature field distribution and analyse the influence of different factors on the quenching effect. A solid heat transfer simulation model for the laser quenching process of 45 steel was established using COMSOL software. The laser quenching test bench was built and the 45 steel laser quenching test was carried out. The solid heat transfer simulation model was optimized through the synergistic analysis method. The average relative error between the peak temperature at the characteristic point and the test data is 3.82%, which is 41.19% lower than that before optimization.
