Analysis of flow and aerodynamic noise behaviour of a simplified high-speed train bogie inside the bogie cavity

open access: yes, 2014
Aerodynamic noise becomes significant for high-speed trains but its prediction in an industrial context is difficult. The flow and aerodynamic noise behaviour of a simplified high-speed train bogie at scale 1:10 are studied here through numerical ...

Laser additive manufacturing of hierarchical multifunctional chiral metamaterial with distinguished damage-resistance and low-frequency broadband sound-absorption capabilities

open access: yesMaterials & Design
Traditional materials or advanced artificially engineered metamaterials are incapable of effectively addressing the simultaneous challenges of impact energy hazards and low-frequency noise.

Investigation of aerodynamic performance of high-speed train by detached eddy simulation

open access: yes, 2012
The detached eddy simulation (DES) is employed to study the flows around the high speed train at speed of 500km/h. Its object is to evaluate the aerodynamic performance. As we know, for high speed trains at speeds bigger than 250 km/h, most (about 75-80%)

Tunnel gradients and aural health criterion for train passengers [PDF]

open access: yes, 2014
An inconvenient consequence of the UIC health and safety criterion for allowable pressure changes in railway tunnels is highlighted. It is shown that the criterion limits allowable speeds in long tunnels with large changes of elevation much more than it ...

Modelling stem cell differentiation related processes—A practical overview for biologists

open access: yesFEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Design and energy absorption performance of gradient-Orowan synergistically strengthened lattice structures

open access: yesMaterials & Design
Lattice structures have attracted much attention in the engineering field due to their light weight, high specific strength, and excellent energy absorption characteristics.

Research on speed control of high-speed train based on multi-point model [PDF]

open access: yesArchives of Transport, 2019
The traditional train speed control research regards the train as a particle, ignoring the length of the train and the interaction force between carriages.
