Abstract: In recent years, the wheeled vehicles without spades are employed in modern military applications due to their enhanced mobility and manoeuvrability. In this work, the dynamic modelling and vibration analysis of six wheeled truck without spades and equipped with recoil mechanism under an impulsive force is studied. A novel spatial vehicle model is developed to describe vibration of the heavy wheeled truck. The governing equations of the system are derived and the obtained vibrational equations are solved and simulated. The simulation results show that the dynamic specifications of the recoil mechanism have prominent effects on the vibration behaviour. Moreover, choosing appropriate values of the system parameters prevents excessive vehicle vibration or lift-off. Finally, it should be emphasised that the novel spatial dynamic model of the wheeled truck with the recoil mechanism can be an innovative benchmark for future studies.

Keywords: wheeled truck; without spades; dynamic modelling; recoil mechanism; firing force; vibration analysis.
