Neither the separate skyhook damping nor inertance control strategy can adapt to variations of both road and load conditions simultaneously. To address this issue, work proposed a novel ideal multi-hook system by combining inerter hybrid damper, with their coefficients optimized. The achieve holding without sacrificing ride comfort. Depending on whether damper were adjusted independently or tog...

In this paper, a state-of-the-art literature review is presented emphasising on the development of control variants for mass damper schemes building-like structures. Additionally, systematic conducted addressing three relevant questions: What type preferable by associated industry? How are dampers distributed around world? Is industry following research? Through review, updated lists implementa...

In an effort to solve the issue of unadjustable damping skyhook inertance suspension, a new adjustable device combining inerter and damper that aims simultaneously adjust was proposed. This article proposes near practical mathematical model such device, is found be equivalent parallel connection damper. A prototype made, its inertial forces are separated through quasi-static dynamic mechanical ...

This paper presents a simulation-based study of the performance achievable by a continuously variable electro-hydraulic semi-active suspension system. By applying state-of-the-art dynamic optimization techniques, a direct optimal controller is developed for a nonlinear quarter car model that includes an identified semi-physical damper model. The direct optimal control approach offers an intuiti...

Inertial mass controllers, including passive, semi-active and active strategies, have been extensively used for canceling human-induced vibrations in lightweight pedestrian structures. Codes to check the vibration serviceability current controller design approaches assume that both excitation forces are same on a flexible structure rigid structure. However, this fact may not be assumable since ...

Conventional skyhook-based ON–OFF control switches the damping force on a vibration suppression target according to sign of product and relative velocities (which is called condition function). Here, we propose strategy that uses novel function for improved performance. The proposed formulated based theory forced with base excitation. Its effect upon semi-active performance investigated via num...

When high-rise buildings are shaken due to external forces, the facilities of building can be damaged. A Tuned Mass Damper (TMD) resolve this issue, but seismic resistance TMD is exhausted detuning effect. The Impulsive Semi-Active (ISAMD) proposed with fast coupling and decoupling at active joint between mass structure overcome proof effects a ISAMD were compared. numerical analysis results in...
