Application of Metastructures for Targeted Low-Frequency Vibration Suppression in Plates
Ghachi, Ratiba F.; Mohamed, Ahmed S.; Renno, Jamil; Alnahhal, Wael ( Springer , 2022 , Article)Purpose We present an approach that combines finite element analysis and genetic algorithms to find the optimal configuration of local resonators created in the host structure to suppress their vibration in a target ... -
Calculating the response of waveguides to base excitation using the wave and finite element method
Renno, Jamil; Sassi, Sadok; Alnahhal, Wael I. ( SAGE , 2021 , Article)The prediction of the response of waveguides to time-harmonic base excitations has many applications in mechanical, aerospace and civil engineering. The response to base excitations can be obtained analytically for simple ... -
Enhancing the damping effect of MRF damper using an external magnetic excitation system
Badri, Yousif; Alhams, Amir; Sassi, Sadok; Hussein, Mohammed; Renno, Jamil ( Institute of Physics Publishing , 2023 , Article)The magnetic field generated by the damper’s magnetic circuit governs the yield stress value of the Magnetroholgical Fluid (MRF) damper and hence its damping effect. This paper contributes to the literature on the development ... -
Experimental and numerical investigation of damping in a hybrid automotive damper combining viscous and multiple-impact mechanisms
Badri, Yousif; Sassi, Sadok; Hussein, Mohammed; Renno, Jamil ( SAGE , 2022 , Article)One of the least investigated approaches in passive vibration control is the possibility of combining different types of dampers that use different damping principles. Such a combination process, if wisely designed and ... -
Investigating the characteristics of a magnetorheological fluid damper through CFD modeling
Badri, Yousif; Syam, Thaer; Sassi, Sadok; Hussein, Mohammed; Renno, Jamil; Ghаni, Sаud... more authors ... less authors ( Institute of Physics Publishing , 2021 , Article)Computational Fluid Dynamics (CFD) analysis is conducted on mono-tube vehicle MRF damper investigated experimentally in a previous study. In this study, the fluid of the type MRF-132DG was inserted inside a damper of a car ... -
Numerical study on the damping characteristics of a shock absorber valve utilizing different velocities through CFD analysis
Badri, Yousif; Syam, Thaer; Sassi, Sadok; Hussein, Mohammed; Renno, Jamil; Ghani, Saud... more authors ... less authors ( National Technical University of Athens , 2021 , Conference Paper)Shock absorbers or hydraulic dampers are power dissipating devices. The fluid flow inside the damper is governed by predefined passages. The damping effect is accomplished by the resistance of oil to flow through the ...
