MODELLING AND SIMULATION OF A FAST 2/2 SWITCHING VALVE

摘要

In this paper a model of a fast 2/2 switching valve is presented, where both the magnetic path as well as the spool assembly are modelled. The model presented here is primarily aimed for system design. In other word, the model must be simple, yet accurate, and with a reasonable number of parameters Some of the parameters are often hard to obtain, especially when it comes to magnetic material properties. In this study, a simulation model of the entire test stand has been utilised in order to parameterise the model against measured data. However, even for major deviations from operational point used for the model adaptation, the model accurately predicts the valve response.
