Abstract
In agricultural vehicles large forces are required to operate the steering axis because of the weight of the vehicles as well as the terrain they operate in. For this purpose hydraulic solutions are applied due to the forces that they are capable of delivering. However, in hydraulics the leakage must always be considered. This report models such leakages in the gearset of Danoss' OSP unit. These leakages cause a drift on the steering wheel of the vehicle which Danfoss are interested in reducing. Modelling the leakages and applying them to a nonlinear model, can be used to further understand what causes these leakages have on the system and could prove a valuable tool to find ways to reduce the leakage. Due to issues with the model the focus of this report has been analysing the OSP hydraulic system to find the cause of the modelling errors.
