Federal Motor Vehicle Safety Standard No. 208 presently contains requirements for a rollover test for vehicles equipped with passive restraint systems. In that test procedure, the test vehicle has no longitudinal velocity and thus the procedure does not closely simulate a real-world highway rollover. The objective of this program was to develop a rollover procedure in which the vehicle is oriented at 45 degrees to its line of travel. Four preliminary tests were conducted in accordance with the current FMVSS No. 208 procedure. Three 1972 Vega hatchbacks and one 1971 Vega notchback were used in these tests. Five 45 degrees Tests were conducted using 1972 Chevrolet Vega hatchbacks. Moment-of-inertia values were determined for one of the test vehicles. Vertical and lateral suspension force/deflection characteristics were measured for all five vehicles. Although the test conditions were controlled as closely as possible the vehicles did not exhibit identical roll characteristics, rolling between 1/2 and 1-1/2 times. The test vehicles were instrumented with linear accelerometers and roll-, pitch-, and yaw-rate measuring devices. Each vehicle contained two test dummies, in the right front and right rear seating positions, instrumented with head and chest triaxial accelerometers.
