Transient Analysis of an EMVD Using COMSOL Multiphysics

G.E. Stebner[1], C. Hartwig[1]
[1]Ostfalia University, IMEC, Wolfenbüttel, Germany

In this paper an EMVD (Electro-Mechanical Valve Drive) for combustion engines is redesigned to achieve a fail-safe behavior when power loss occurs. The AC/DC Module and the Moving Mesh interface of COMSOL Multiphysics 4.2 are used to build up a transient model. This model also includes the calculation of eddy currents.
