AN EXPERIMENTAL AND NUMERICAL INVESTIGATION OF THE COMBINATION OF DIFFERENT DAMPER TYPES FOR IMPROVED CONTROL OF VIBRATION
BADRI,YOUSIF BABIKIR ALI BABIKIR (2022 , Master Thesis)Eliminating and reducing unwanted vibrations required a good knowledge of the dynamic systems fundamental components; mass, spring, and damper. Meanwhile, dampers are responsible for reducing the vibrations amplitudes and ... -
Effect of rail unevenness correlation on the prediction of ground-borne vibration from railways
Ntotsios, Evangelos; Thompson, David; Hussein, Mohammed ( DC/ConfOrg , 2015 , Conference Paper)This paper presents the influence of rail unevenness correlation on the predicted track and ground vibration. The study is based on an integrated railway model in the wavenumber-frequency domain with varying complexity ... -
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 ... -
Experimental validation of a numerical model for the ground vibration from trains in tunnels
Jin, Qiyun; Thompson, David; Lurcock, Daniel; Toward, Martin; Ntotsios, Evangelos; Koroma, Samuel; Hussein, Mohammed... more authors ... less authors ( DC/ConfOrg , 2015 , Conference Paper)Ground vibration and ground-borne noise from trains in tunnels are attracting increasing attention from researchers and engineers. They are important environmental issues related with the operation of underground networks ... -
Geomechanical Modelling of Railroad Ballast: A Review
Alabbasi, Yahia; Hussein, Mohammed ( Springer , 2019 , Article)Traditional ballasted tracks have been used intensively around the world with ballast as the main material for tracks. Ballast has a significant contribution to the track alignment, stability and sustainability. After ... -
Ground-borne vibrations due to railway traffic in urbanized areas: A numerical study about traffic in trench cross-sections
Pinto, Alexandre; Costa, Pedro Alves; Colaço, Aires; Lopes, Patrícia; Hussein, Mohammed ( National Technical University of Athens , 2017 , Conference Paper)Modern cities require efficient mass transportation systems like subway and railway networks. Due to the lack of available space and also due to environmental concerns, it is usually preferable to use the underground space ... -
Modelling the dynamic pile-soil-pile interaction in a multi-layered half-space
Hamad, Waleed; Ntotsios, Evangelos; Hunt, Hugh; Hussein, Mohammed; Thompson, David; Talbot, James... more authors ... less authors ( DC/ConfOrg , 2015 , Conference Paper)Within the context of railway ground-borne vibration, the dynamic pile-soil-pile interaction remains an area that has not been sufficiently investigated. Whilst a number of researchers have scrutinised the vibration response ... -
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 ... -
The PiP model and progress in ground vibration from railways
Hussein, Mohammed; Hamad, Waleed; Hunt, Hugh ( Australian Acoustical Society , 2017 , Conference Paper)Vibration in the ground causes problems. At large amplitude vibration causes damage, the most obvious example being earthquake damage. But the ground motion in a damaging earthquake is typically low-frequency (below 1Hz) ... -
The effect of track load correlation on ground-borne vibration from railways
Ntotsios, Evangelos; Thompson, David; Hussein, Mohammed ( Academic Press , 2017 , Article)In predictions of ground-borne vibration from railways, it is generally assumed that the unevenness profile of the wheel and rail is fully correlated between the two rails and the two wheels of an axle. This leads to ... -
