In his new commentary, Damper re-emphasises his claim that parity is not a generalisation problem. But when proper account is taken of the arguments he puts forward, we nd that the proposed conclusion is not the only one that can be drawn. In adding the word`still' to the title of his ongoing commentary, Damper re-emphasises his claim that`parity is not a generalisation problem.' His view is th...

This research paper represents the analysis and simulation of semi-active suspension using non-linear modeling Magneto-Rheological (MR) with consideration hysteresis behavior for a quarter car model. The is based on assumption that each wheel experiences same disturbance excitation. Hysteresis analyzed Bingham, Dahl's, Bouc-Wen models. focuses passive, Dahl, models five road profiles. desired d...

In this paper, we describe the design and manufacturing of a viscous inertial mass-damper (VIMD) prototype. The damper parameters, mass, damping coefficient can be continuously adjusted. Experimental validations were carried out on VIMD with various parameters scaled sagged cable 19.47 m long for vibration mitigation, along simulation study using finite element method (FEM). experimental result...

Propeller-induced longitudinal vibration resonance in marine propulsion shafting systems causes great harm to the hull structure and is primary source of shipboard noise. Integrating a friction damper with designed parameters into thrust bearings can prevent these issues. To investigate performance damper-integrated bearing transmission control, an experimental theoretical study carried out lab...

Knitted fabrics are widely used by the underwear apparel industry due to their good elasticity. Modeling the mechanical behavior of knitted fabrics using Kelvin model is one of the discussed subjects in the textile industry. The purpose of this study is to investigate the accuracy of a nonlinear Kelvin model for determining the drying behavior of knitted fabrics. To fulfill this aim, genetic al...

The present study focuses on the estimation of response building structure supplemented with superelastic shape memory alloy (SMA) damper under stochastic seismic excitation. To this end, has been determined using linearization method random earthquakes and control efficiency SMA is compared yield damper. As output, top floor root mean square (rms) acceleration displacement are presented here i...

This paper investigates the application of semi-active inerter in semi-active suspension. A semi-active inerter is defined as an inerter whose inertance can be adjusted within a finite bandwidth by on-line control actions. A force-tracking approach to designing semi-active suspension with a semi-active inerter and a semi-active damper is proposed, where the target active control force derived b...

This paper presents the stability and bifurcation analysis of a nonlinear thermoacoustic model consisting of a combustion chamber coupled to a Helmholtz damper. Only the acoustic mode in the cavity of the combustion chamber to which the Helmholtz damper is tuned is considered. The Helmholtz damper includes a non-smooth damping term and can be seen as a tuned vibration absorber with a coupling o...

Squeeze film dampers are widely used in aircraft engines, land-based gas turbines, and other rotating machines to improve system damping. They often have entrained air within the oil film, which is usually not taken into account in rotordynamics analysis due to lack of good formulations of the effects involved. The effects on the damping force calculation can be significant. This work presents ...
