Abstract [en]

Simulation is a great tool to help the development of products. For simulation to be a validtool there are high demands on the models, where they need to be accurate and fast, regardingcomputational time.  This work is a first step to model and implement a 4 wheel drive system.The system is electronically controlled and the torque transferred by the system is dependenton the pressure built up by the hydraulic system. This work focuses primary on the develop-ment of the solenoid pressure control valve model. In order to perform simulations, the valvemodel needs to be connected to the rest of the system. The supply pressure is provided froma piston accumulator, that is implemented only to provide the right functionality at this stage.The load in this system is composed of a wet multiplate clutch, that is implemented only as astatic model based on measurements. The modeling of the valve was divided into studying theelectromagnetical part and hydromechanical part separately. The electromagnetical part, i.e.the solenoid, is modeled as a resistor in series with a nonlinear inductor. The electromagneticcharacteristics is modeled with the help of a curve fitting technique. A testbench was developedfor this purpose. The simulation results of the solenoid agrees well with measured results. Alinearized analysis of the hydromechanical part was performed in order to better understand thedynamics of the valve and see the most dominant effects. Two valve configurations resultedfrom this work. One includes more dynamics and has the possibility to change more param-eters in order to study different effects. The other configuration was based on the linearizedanalysis and therefore includes only the most dominant dynamics. This model is much fasterto simulate. Both configuration shows accurate results when compared to measurements of thesystem.
