Methods for estimating hysteretic behavior and vibration responses of a timing belt tensioner

Advances in Mechanical Engineering, 2019
An automatic tensioner that consists of a torsional spring and friction damping elements is widely used in belt drive system. The relation of the applied torque versus the imposed angle of tensioner during loading and unloading processes is described as ...

The numerical calculation method based on equivalent frequency-independent time-domain damping model

Journal of Low Frequency Noise, Vibration and Active Control, 2022
In order to realize the time-domain analysis based on hysteretic damping model, the frequency-independent time-domain damping model of single degree of freedom (SDOF) system is constructed.

Low Cycle Repetitive Loading of Ti‐6Al‐4V‐Epoxy Composite Lattice Structures for Enhanced Energy Dissipation and Damage Tolerance

Advanced Engineering Materials, EarlyView.
Composite Ti–6Al–4V–epoxy lattice structures are additively manufactured and epoxy infiltrated for cyclic loading. At low lattice volume fractions, hybridization produces synergistic gains in stiffness and energy dissipation. At higher volume fractions, synergy diminishes, although composites still exceed metallic lattices in specific energy ...

Clamp Nonlinear Modeling and Hysteresis Model Parameter Identification

IEEE Access, 2021
Based on the Bouc-Wen model, a nonlinear hysteretic restoring force model is established with dynamic equations. The hardening and softening of the material after reaching the yield limit are described by the nonlinear restoring force-displacement ...

Multiscale Architecture and Mechanics of the Cell Nucleus: Implications for Disease, Bioengineering and Nanomedicine

Advanced Science, EarlyView.
Nuclear mechanical properties are inherently scale‐dependent, arising from a hierarchical architecture that spans DNA, chromatin, the nuclear envelope, and condensates. Experimental techniques and theoretical models are integrated into a cohesive multiscale framework linking nanoscale structural features to organelle‐level mechanical behavior.

Bouc-Wen model of hysteretic damping

Procedia Engineering, 2017
Abstract In this work we consider the dynamics of a mechanical system under external force with a damping part taking into account the hysteretic nature of the damper. As a mathematical base of the hysteretic damper we use the Bouc-Wen model. The simulation results in the form of the force-transfer function and demonstrates the “efficiency” of the ...
