激光内割过程温度场的数值模拟

The numerical simulation of temperature field during laser inner cutting

对激光内割快速原型系统中激光焦点与透明聚合物材料内部作用后的温度分布进行了研究 .在传热学的基础上建立了激光焦点在透明材料内部作用时的温度场模型 ,借助于大型有限元分析软件ANSYS进行了数值模拟 .数值模拟结果与实验现象相符 ,不仅为优化激光内割系统的工艺参数提供了理论依据 。

The temperature field caused by focused laser in transparent polymer was studied. Based on heat transferring, a thermal field model of Laser Inner Cutting system was established and numerically simulated with the help of finite element software ANSYS. The results agree with the experiments. This study not only provides theoretic basis, but also gives explanation of some phenomena during the experiment.
