When an elastomer approaches or retracts from adhesive indenter, the elastomer’s surface can suddenly become unstable and reshape itself quasi-discontinuously, e.g., when small-scale asperities jump into snap out of contact. Such dynamics lead to a hysteresis between approach retraction. In this study, we quantify numerically analytically ensuing unavoidable energy loss for rigid indenters with...

Hysteresis motors are self starting brushless synchronous motors which are being used widely due to their interesting features. Accurate modeling of the motors is crucial to successful investigating the dynamic performance of them. The hysteresis loops of the material used in the rotor and their influences on the parameters of the equivalent circuit are necessary to be taken into considerat...

This paper presents 2D and 3D modeling of hysteresis motor using high temperature superconducting element Yttrium Barium Copper Oxide (YBCO) in the rotor. These hysteresis motors aim to improve the performance in comparison with that of conventional hysteresis motors. Various performance parameters of high temperature superconducting hysteresis motor are computed from the proposed 2D and 3D mod...

In some systems with hysteresis behavior like Shape Memory Alloy (SMA) actuators and Piezo actuators, we essentially need an accurate modeling of hysteresis either for controller design or performance evaluation. One of the most interesting Hysteresis non-linearity identification methods is Preisach model in which hysteresis is modeled by linear combination of elemental operators. Despite good ...

hysteresis has been widely recognized in the soil water relationship. in this paper, a detailed review of hysteresis was performed in relation to its models. so far, different models have been suggested to describe hysteresis in the water retention curve (wrc) that could be categorized into two main groups: conceptual and empirical models. the models in the first group are based on the domain t...

This paper presents a model of a thermostatic valve based on first principles and where the hysteresis effect is modelled using an adaptive model for friction compensation. The grey box modelling approach is applied, i.e. both physical interpretation and statistical methods are used to build and validate the suggested model. The model performance is illustrated using empirical data and issues c...

A modeling technique for rate-independent ~quasistatic! scalar magnetic hysteresis is presented, using neural networks. Based on the theory of dynamic systems and the wiping-out and congruency properties of the classical scalar Preisach hysteresis model, the choice of a feed-forward neural network model is motivated. The neural network input parameters at each time step are the corresponding ma...

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 applica...

The main contribution of this paper is the development of a linearized model for describing the dynamic hysteresis behaviors of piezoelectrically actuated fast tool servo (FTS). A linearized hysteresis force model is proposed and mathematically described by a fractional order differential equation. Combining the dynamic modeling of the FTS mechanism, a linearized fractional order dynamic hyster...

This paper presents a mathematical theory for modeling the hysteresis phenomenon observed in trac ̄ow. It proposes that acceleration, deceleration and equilibrium ̄ow should be distinguished in obtaining speed-concentration and/or occupancy relationships, such that the phase transitions from one phase to another can be correctly identi®ed. The analysis shows that the speed±concentration curves ...
