Abstract

The purpose of this paper is to introduce a systematic approach for improving and optimizing the ride performance in space rovers on wheels. Quarter rover models (QRM) are in use for years to study the static and dynamic behaviour of the rover. The parametric investigation studies the behaviour of steady state response on static and dynamic conditions of road through the influence of multiple rover’s characteristics. Some of rover parameters are considered including the trailing arm length, wheel radius, trailing arm angle, wheel rotation angle, damping ratio and torsional spring rate, etc.
The analysis of results put forward a key-tuning parameters for improving the ride specifications of space rovers under normal operating conditions.
