説明

In order to research on the behaviors of destruction of carbon steel forgings by impact bending, we designed an impact testing machine of drop hammer type. The total height of this testing machine is about 5m. The weights of the used drop hammers are 12.5, 25 and 50kg respectively. The maximum distance from the position of test piece to the drop hammer is 3.200m. Consequently, the maximum energy of impact bending of this testing machine is 160kgm.<br>The induced resistance forces of test pieces at impact bending were measured by the strain quantities of the strain gages which had been pasted on the canti lever beams used as supports for test piece.<br>The drop hammer fell naturally, with an initial velocity=zero. The absorbed energy of the test piece at impact bending, could be calculated from the measured area of the induced resistance forces versus the destruction time curve.
