CENTER OF GRAVITY HEIGHT: A ROUND-ROBIN MEASUREMENT PROGRAM

A round-robin center of gravity height measurement study was conducted to assess current practice in the measurement of the vertical position of the center of gravity (c.g.) of light truck-type vehicles. The study was performed by UMTRI for the Mototr Vehicle Manufacturers' Association. Chrysler, Ford, General Motors and the National Highway Traffic Safety Administration perticipated. The primary objectives were (i) to determine to what extent the differing experimental procedures currently used by the participating laboratories result in significant differences in the measured vertical position of the center of mass of light truck-type vehicles, and (ii) to gain insight into the physical causes of such differences. The results of the program shoved (i) that there were significant differences between the c.g. height measurement results obtained by different laboratories, (ii) repeatability of results within the individual laboratories was generally good, and (iii) close examination of the individual procedures tended to explain the differences in results between laboratories, this providing the expecctation that variability in this regard could be significantly reduced.
