Abstract Based on the non-linear dynamic simulation principle and the theory of thermal-structure coupling, a complete thermal-structure coupled analysis of this energy-absorbing process was made in finite element software LS-DYNA. The cutting force and energy dissipation curve was obtained, The results showed that peak value didn’t appear in the impact force curve，and the force value kept stable in the calculate. The energy dissipated by cutting heat accounted for 21% of the total impact energy, then, the influence of cutting heat should be considered during the simulation of cutting energy-absorbing process. Based on thermal-structure coupled analysis, The affection regularity of impact speed, cutting section parameters and tool parameters to mechanical characteristics of cutting energy-absorbing process was studied.

Key words： cutting energy-absorbing thermal-structure coupled cutting heat impact velocity cutting section parameters tool parameters
