Abstract

Based on the solution of energy equation about thermal conduction, a semi-analytical method to calculate the temperature field in a thin metallic plate irradiated by CO₂ laser beam was presented in previous study. By means of this method, the simulation of temperature field can be completed on a personal computer with less calculation burden. In this paper, this method is studied further. The problem existed in the current model is pointed out. Via simplifying mathematical formulas rationally, an improved practical model to simulate the temperature distribution is given. According to the model, a set of simulation software is developed to calculate temperature distribution under laser heating opaque materials. The simulation with respect to a thin stainless steel sample plate heated by CO₂ laser beam is carried out. The comparison of theoretical simulation and experimental data is made. The calculation error is less than 10%.
