Abstract：

Based on thermal-mechanical coupling theory and virtual work principle, the display mechanical model of forging process was established. The changes of the mechanical characteristics in the forging process and the dynamic characteristics in different working conditions of forging part were analyzed by LS-DYNA software. The results show that the stress and strain as well as impact load of the forging part increase gradually with the increase of hitting energy; the impact load of forging part decreases gradually when the forging temperature rises under the same hitting energy and different initial temperatures. The analysis results will help to obtain the required hitting energy of forging part forming accurately in order to achieve the objects of energy-saving and environmental friendly methods and reduce the impact on forging equipment as well.
