Abstract
A system for capturing and analyzing the load/time signals generated during a drop tower impact event has been developed and calibrated using static calibration techniques. The calibration factors for the four ranges available to this system were 624.86 kN/V, 318.00 kN/V, 117.01 kN/V and 63.89 kN/V. The total impact energy of ASTM E604 specimens fabricated from CSA G40.21 350 WT and tested at 1.5 m/s were within the scatter band of these previously characterized specimens.
