Abstract
The new technological process to form deep hole in relative thin panel by friction heat not only saves material, but also obtains workpieces with high performance. The thermal analysis about friction heat and force about friction forming hole is one of key technology problems. In this paper, the model of temperature field and stress field are observed with LS-DYNA based on dynamic two sliding friction pair coupling model structure, then the temperature changes of the workpiece under different conditions are studied. The mathematical model verified the correctness of the simulation in this paper, and laid a foundation for further research on deep hole process by friction heat.
