Abstract: Due to extensive implementation of the spade-less wheeled vehicles in advanced military services, their design and analysis have received a great deal of interests in recent years. In this work, performance of some recoil mechanisms in elimination of the huge firing force of an installed artillery system on the vehicle are studied and compared. To do this, at first, a novel spatial vehicle model is developed to describe vibration of the spade-less vehicle equipped with several recoil mechanisms such as passive, soft and magnetorheological ones. The vibration equations of such vehicle are derived and simulated. The simulation results indicate the importance of the recoil mechanism and demonstrate the priority of the magnetorheological damper. Furthermore, the new spatial dynamic model of the wheeled vehicle with various recoil mechanisms can be a basic benchmark for the future studies.

Keywords: wheeled vehicle; spade-less; nonlinear dynamics; recoil; magnetorheological; vibrations.
