Dynamics of Wheeled Vehicles. Report 4. A Statistical Analysis of Obstacle-Vehicle-Speed Systems.

Abstract

Approximately 300 tests were conducted with an M37 3/4-ton truck at various speeds over single obstacles of various heights and shapes. Data for acceleration-time-history, vehicle speed and pitch angle, and event markings were recorded on FM analog tape, which was processed by an analog computer (described in Appendix A). The following parameters were determined (at the vehicle center of gravity) for each test: (a) peak, root mean square, and mean root mean square values of vertical acceleration, and the vector sum of vertical and longitudinal acceleration components; and (b)vehicle impact speed and average speed during obstacle traversal. Linear correlations of vehicle average speed with peak and statistical accelerations were determined by regression analysis. (Author)
