MODELLING OF MAGNETIC FIELD OF ELASTOMAGNETIC PRESSURE FORCE SENSOR IN COSMOS/EMS ENVIROMENT

The article deals with magnetic field modelling which is present in ferromagnetic core of elastomagnetic force sensor (EMS). EMS is based upon utilization of Villari´s effect and belongs to nonlinear systems group. The solution of such field is possible by partial differential equation of vector magnetic potential in nonlinear environment. However, solution of such equation is very difficult, so it is essential to find proper tool. In this case, COSMOS/EMS software, which utilizes the method of finite elements, was used.
