Topic: A - Methods and tools for multi-disciplinary systemsThe development of pressure valves is characterized by a large amount of lab testing. Virtual prototyping using non-linear simulation allows to make the development process faster and cheaper. The paper presents a concept as well as some selected methods of a virtual prototyping tool of this type. An existing proportional pressure control valve is used to develop a model which contains the entire system. That means to model hydraulics and mechanics as well as magnetics and electrics. The main point of the paper is to show the possibilities of parameter detection using geometrical or material data. First, hydraulic resistances are used to demonstrate how parameters are determined with analytical approaches. More complex geometries require the employment of numerical methods like CFD. A physics-based model of a proportional solenoid is presented. Two typical elements of a reluctance network are used to illustrate parameter detection from geometry. The performance of the entire model is compared with measurements and notes are included about model and parameter quality.
