Abstract

This paper presents a novel study of the handling characteristics in space rovers operating on rough terrains. The proposed approach implements a detailed mathematical model comprising individual rigid bodies, force elements, and suspension mechanisms of the rover. The proposed work is focused on correlated dynamics of the suspension mechanism considering adjustable and tuneable design parameters. To this aim, a set of arbitrary operating conditions,
namely, static loading, step-input, and irregular road profiles, are defined to investigate the influence of each parameter on ride comfort, rover agility, and stability of the suspension mechanism. The main contribution of this study can be pointed out as highlighting the mist significantly-influencing design parameters and defining correlated break-points for the rover design, to adjust and tune the dynamic response of the suspension system according to the characteristics of irregular terrains. Moreover, the proposed work provides scholars and researchers with a user-friendly benchmark for further analysis and optimal design attempts of space rovers.
