摘　　要：利用有限元计算软件Ansys模拟CO2激光匀速圆周运动作用下膏药材料产生出透气小孔的模型.计算结果表明:在连续CO2激光作用下,仅需几毫秒时间就可以使膏药材料烧穿,制备透气孔的大小随着光斑中心圆周运动轨迹半径的增大而增大.当激光速率达到3 m/s以上时,激光速率的变化对制孔直径和制孔深度几乎没有影响.A model of drilling on sticking plaster using a continuous CO2 laser to do uniform circular motion irradiated sticking plaster to vaporize is studied. Numerical simulation by using finite element analysis software Ansys is applied. The simulation result shows that, sticking plaster material to vaporize need only a few milliseconds heated with continuous CO2 laser, and the size of the hole is calculated to increase with the radius of beam central circular motion trajectory. While laser velocity up to 3 m/s or more, the wide and depth of the hole are almost no effect.
