| Abstract: | Points out some factors of error in measurement by the general formula. By a new special device, analyzes and affirms that a part of energy is neglected by previous method and existed truly. Based on practical measurement, proposes a corrected formula to calculate the impact energy. The mains are. 1 ) the velocity used to the calculation should be considered as the terminal velocity of screw after reverse operation, but not the instant velocity of slider contacting with forging, 2) the potential energy releasedr fom forging deformationm ust be cotained in the impact energy. |
