| Abstract: | The mathematics model is set up according to the characteristics and actual process environment of the laser drilling. The finite element method and limited difference method are used to calculate the numerical value of temperature field in the laser drilling process. The temperature field is simulated by ANSYS, and the depth, the time characteristic and the variety curve with the laser energy of the pore are gotten. The basis for choosing the parameters of laser drilling is offered. |
