AN INVESTIGATION OF THE ROLLOVER DYNAMICS OF A MILITARY VEHICLE

摘要

The state of the art in simulating the dynamic behavior of road vehicles is summarized and then applied to a specific military vehicle (the M-151) to determine the operating conditions and maneuvers that are likely to cause rollover. The findings obtained by means of simulation confirm and explain the rollover experience of the M-151 and also suggest why drivers of the M-151 nay inadvertently bring the vehicle to an operating state in which the potential for rollover is large, given a need for some emergency steering or braking control. The simulation findings are examined to determine the feasibility of synthesizing a rollover index for use either as (1) a guide in assessing the suitability of a given vehicle for a given mission or (2) providing a warning to drivers such that they can avoid operating states promoting a rollover response.
