Abstract
An apparatus 10 for measuring and/or analyzing the rollover characteristics of a vehicle 12. Apparatus 10 includes a controller 14, a selectively movable test fixture assembly 16, a truck or towing vehicle 18 which is coupled to trailer assembly 16 and which selectively tows or drives assembly 16, several cameras 22, 24, 26 and 28, and a user interface 30. Vehicle 12 is attached to test fixture 16, and user interface 30 is used to activate motor assembly 36 which selectively rotates vehicle 12 to a desired roll angle 90 relative to the ground surface 43. Once vehicle 12 is correctly positioned, an operator drives truck 18 at a predetermined and desired speed. Controller 14 generates release signals to exploding bolts 86, 88, which simultaneously explode, thereby releasing vehicle 12 from frame 32. In this manner, apparatus 10 allows the drop height and the translational and vertical velocity of a vehicle to be selectively controlled, adjusted and repeated from test to test, and provides controllable and predictable roof-to-ground impacts.
