Volume 7A: Dynamics, Vibration, and Control, 2021 Abstract Several structures of important industrial relevance feature large-amplitude vibration, which can have an initially hardening or a softening behavior. Models with quadratic and cubic nonlinear stiffness terms are often used to predict the nonlinear dynamics of such structures. If boundary conditions constitute an important cause

Equivalence of Bilinear Hysteresis and Viscous Damping Energy Dissipation
Journal of Testing and Evaluation, 2023 ABSTRACT To evaluate the energy dissipation differences between metal dampers and viscous dampers and to gauge the degree of equivalence between bilinear hysteresis and viscous damping, we studied the equivalence of bilinear hysteresis and viscous damping.

Dynamic characteristics and adjustment of vibration isolators using the bilinear hysteresis
Proceedings of Higher Educational Institutions. Маchine Building, 2022 The paper considers dynamic characteristics of a vibration protection device with bilinear deformation diagram and hysteresis behavior as part of a system with one degree of freedom. Based on results of the numerical simulation of the system’s response to harmonic effects, the amplitude-frequency characteristics (AFC) of relative displacements and ...

Parametric Excitation of a Pendulum With Bilinear Hysteresis
Journal of Applied Mechanics, 1970 The steady-state responses of a simple pendulum with a hinge exhibiting bilinear hysteretic moment-rotation characteristics and parametrically excited by a sinusoidal oscillation at the base is given. The stability of the steady-state solutions is discussed.

Vibration of a Cantilever with Bilinear Hysteresis
Transactions of the Canadian Society for Mechanical Engineering, 1988 This paper presents a vibrational analysis of a two layer beam with weak hysteresis caused by structural damping between layers. Analysis was performed using the Krylov-Bogoliubov-Mitropolski asymtotic method. Qualitative results in the form of plots relating to free, steady-state and nonstationary vibration are presented.

Bilinear product Preisach modeling of magnetic hysteresis curves
International Magnetics Conference, 1989 The classical Preisach model has been unified using population dynamics, resulting in a bilinear product model. A practical numerical procedure has been devised for the calculation of the model parameters from measured magnetization data. Experimental magnetization curves have been analyzed by this method to obtain the material parameters and the ...

ACTIVE CONTROL OF BUILDINGS WITH BILINEAR HYSTERESIS AND TIME DELAY
International Journal of Structural Stability and Dynamics, 2013 In this paper, an active controller for buildings with bilinear hysteresis and time delay is studied. The bilinear hysteretic model is treated as a stiffness restoring force. By using specific transformation and augmentation of state parameters, the equation of motion of the system with an explicit time delay is transformed into a standard state space

Sinusoidal Excitation of a System With Bilinear Hysteresis
Journal of Applied Mechanics, 1960 Many physical systems exhibit hysteresis which may be adequately described by a bilinear hysteresis model. This paper considers the response of such a system to sinusoidal excitation. It is shown that the system exhibits a soft-type resonance with stable, single-valued response curves. For such a system it is shown that there exists a critical value of

On Stability of a Circulatory System With Bilinear Hysteresis Damping
Journal of Applied Mechanics, 1969 Dynamic stability problems of a two-degree-of-freedom system with bilinear hysteresis damping and subjected to a circulatory force are considered. Steady-state oscillations and critical loads for flutter of the system are investigated using energy considerations and the method of slowly varying parameters. Problems concerning stability limits (limiting

Tuned Mass Dampers for Structures with Bilinear Hysteresis
Journal of Engineering Mechanics, 1996 A design method of tuned mass dampers (TMDs) for structures with bilinear hysteresis subject to harmonic excitation is proposed. Conventional TMDs fail to control a bilinear structure as the equivalent natural frequency of the structure diverges from the TMD natural frequency at the higher level of excitation.
