摘　　要：运用Ansys有限元分析软件模拟了环状激光束辐照Zn S、Ti O2及Si等材料表面而形成的温度场及应力场分布,并分别研究了同一热源对不同材料及不同热源对同一材料的作用效果.研究结果表明,当同一热源作用在不同材料上时,产生的温度场变化较大,而应力场的变化不大,只是形变的整体幅值产生变化;当不同热源作用在同一材料上时,温度曲线的梯度变化较大,而对应力形变的影响较小.In this paper, the distribution of the temperature field and the stress field formed in the surface of ZnS, TiO2 and Si and other materials irradiated by ring laser beam were simula- ted by using of the finite element analysis software of Ansys, and the effects of different materi- als and different heat sources on the same materials were studied respectively. The research re- sults show that when the same heat source is acting on different materials, the temperature field changes greatly, and the stress field changes little, only the overall amplitude of the deforma- tion changes. When the different heat sources are acting on the same material, the gradient of the temperature curve changes greatly, and the effect of the stress deformation is small.
