Modeling of a non-linear conductive magnetic circuit. 2. Bond graph formulation

We have presented in "Modelling of a non-linear conductive magnetic circuit-Part 1: Definition and experimental validation of an equivalent problem" a non-linear dynamic model in the case of simple shaped magnetic circuit. In order to describe easily coupled electric-magnetic-mechanic problems, a general method using Bond Graph techniques is proposed. The method, tested in the case of electrical coupling, has been implemented in the P.A.C.T.E simulator. The experiment gives results in accordance with the simulated ones.
