Abstract
In the study, the potential for improvement in the ride performance of the Military vehicle M113-A1 is investigated using alternate advanced suspension systems such as active and semi-active suspensions, in place of the existing passive system. The active suspension system is designed to minimize the maximum acceleration of the hull CG and its relative motion with respect to its road wheels. In semi-active (SA) suspension system, desired damping forces are generated by modulating fluid flow through damping orifice based on certain control laws similar to active systems. In this study, three types of SA-suspension systems are considered. The first and second type of SA-suspension systems are based on sky-hook control scheme in which the motion of the hull CG is controlled using absolute and relative velocity feedback signals. The third SA-suspension system controls the motion of the hull CG using the relative velocity and relative displacement feedback signals. Prior to studying the M113 vehicle, both active and semi-active suspension systems were investigated using simpler vehicle models, represented by 1, 2 and 4 D-O-F in-plane mathematical models.
