Dynamic Preisach Model Identification Applying FEM and Measured BH Curve
نویسنده
چکیده
Dynamic hysteresis modeling and its application in numerical field analysis are challenging tasks. This paper presents a measurement system to realize and to measure frequency-dependent behavior of ferromagnetic hysteresis. The well-known static Preisach model of hysteresis has been extended to simulate the dynamic behavior. The full paper will present the model in detail as well as its application in the numerical field analysis of the measurement setup. Keywords—magnetic hysteresis; losses, FEM

A Preisach model identification procedure and simulation of hysteresis in ferromagnets and shape-memory alloys
A Preisach model able to adjust to different systems with hysteresis is presented. The related identification scheme involved uses data from a major hysteresis curve and a least-squares error minimization procedure for the parameters of the characteristic density. The output sequence, f ðtÞ; is obtained by integrating the characteristic probability density function, rða;bÞ; of the elementary hy...
متن کاملA compressive sensing-based approach for Preisach hysteresis model identification
The Preisach hysteresis model has been adopted extensively in magnetic and smart materialbased systems. Fidelity of the model hinges on accurate identification of the Preisach density function. Existing work on the identification of the density function usually involves applying an input that provides sufficient excitation and measuring a large set of output data. In this paper, we propose a no...
متن کاملMaximum Allowable Dynamic Load of Flexible 2-Link Mobile Manipulators Using Finite Element Approach
In this paper a general formulation for finding the maximum allowable dynamic load (MADL) of flexible link mobile manipulators is presented. The main constraints used for the algorithm presented are the actuator torque capacity and the limited error bound for the end-effector during motion on the given trajectory. The precision constraint is taken into account with two boundary lines in plane w...

متن کاملPreliminary results on multi-body dynamic simulation of a new test rig for wheel-rail contact
The ability to perform rolling contact fatigue (RCF) experiments in wheel–rail material is provided by a new small–scale test rig, manifesting the actual dynamic behaviour of the railway system. In this paper, a multi-body dynamics (MBD) model is proposed, simulating the vibration behaviour of the prescribed rig. The new testing facility is modelled using a three-dimensional model of the vehicl...
