The objective of this paper is to describe the modelling and simulation of a hydrostatic steering of an agricultural tractor and to analyze its behavior sensitivity from the point of view of the driver effort requested during steering.
The steering system of a vehicle impacts on the vehicle performance, safety and on the driver’s comfort. Moreover, in off-road vehicles using hydrostatic steering systems, the energy dissipation also becomes a critical issue. These aspects push and motivate innovation, research and analysis in the field of agricultural tractors. This paper proposes the modelling and analysis of a hydrostatic steering system for an agricultural tractor to calculate the performance of the system and determine the influence of its main design parameters.
