Abstraction Level - Power Steering Example Power steering example Can we build the complete system model with a CADbasedsoftware? No, since we have no CAD at this stage of designCan we simulate it within an acceptable simulation(computational) time making use of 3D only methods? No, no 3D software is able to do that ModelWe need another approach to :• Pre-design such systems• Choose an architecture (hydraulic, electrohydraulic,electric)• Assess key functions of the system8 copyright LMS International - 2010
