of the impactor-sled and the top-can were captured through camera #3 (2,000 fps) and camera #2 (1,000 fps), respectively. All the HSCs were triggered simultaneously once the trigger tape was touched (Fig. 37.2b). Thermal images of the bottom-can were obtained using an IR thermal camera (500 fps) shown in Fig. 37.3. The IR camera was triggered as the platform-sled passed through the optical sensor located near the wall. Figure 37.4 illustrates the locations of targets and six accelerometers in the sled system. These accelerometers were used to obtain axial deceleration and off-axis accelerations of the sled-beam. The off-axis accelerations were measured using a triaxial Fig. 37.3 Locations of high-speed cameras (HSCs) and IR camera (IRC) Fig. 37.4 Locations of targets and accelerometers 37 Rigid Angular Impact Responses of a Generic Steel Vehicle Front Bumper and Crush Can. . . 251
