This paper presents a framework to systematically investigate the high-speed train–track–bridge dynamic interactions, aiming provide method for analysing and assessing running safety ride comfort of trains passing through bridges, which are critically important design new railway bridges. Train–track–bridge interactive mechanism is illustrated. A fundamental model established in vehicle subsystem coupled with track spatially interacted wheel–rail model; bridge by track–bridge interaction...
This paper presents an experimental investigation on the effect of replacement natural coarse aggregate (NCA) with either recycled concrete (RCA) or clay brick (RBA) compressive strengths hardened concrete. Two grades (C25 and C50) were investigated, which achieved by using different water-to-cement ratios. In each grade five rates, 0%, 25%, 50%, 75% 100% considered. order to improve performance aggregates in mixes, RCA RBA carefully sieved optimal degradation. this way largest reduction...
A NbMoTaWVTi refractory high entropy alloy (HEA) has been successfully synthesized by mechanical alloying (MA) and spark plasma sintering (SPS). The microstructure properties of this are investigated. It is observed that only two types body-centered cubic (BCC) solid solutions formed in the powders after ball milling for 40 h. However, a new face-centered (FCC) precipitated phase BCC matrix bulk material consolidated SPS. FCC identified as TiO, due to introduction O during preparing process...
Some aerodynamic results about the effect of moving train on aerodynamics train-bridge system in crosswinds are introduced using a computational fluid dynamics (CFD) method. In simulation, new overset mesh approach is applied to present motion trains, and compared with that scaled wind tunnel experiment validate accuracy algorithm. Besides, characteristics associated bridge discussed for range resultant yaw angles. It found angle significantly important performances interaction nose head-car...
Non-Hodgkin's lymphoma incidence rates vary between European and Asian populations. The reasons remain unclear. This two-sample two-step Mendelian randomisation (MR) study aimed to investigate the causal relationship anthropometric indicators (AIs) diffuse large B-cell (DLBCL) follicular (FL) possible mediating role of basal metabolic rate (BMR) in Europe.
For high-speed railways (HSR) in wind prone regions, barriers are often installed on bridges to ensure the running safety of trains. This paper analyzes effect a train cross winds when it passes bridge. Two simply-supported (S-S) PC China, one with 32 m box beams and other 16 trough beams, selected perform dynamic analyses. The modeled by 3-D finite elements each vehicle multi-rigid-body system connected suspension springs dashpots. excitations vehicles numerically simulated, using static...
The rated suspension gap of a low-to-medium-speed maglev train with electromagnetic is normally 8–10 mm. However, while either passing over bridge or being stationary on one, the deforms and therefore alters gap. Hence, problem arises due to coupled vibrations between its supporting bridge. In study reported here, field experiments were conducted Chinese Changsha line, which was first commercial line in China. focus two types pre-stressed double-track concrete bridges line. One simply...
The mechanical characteristics of CRTS III (China Railway Track System III) slab ballastless track structure under high-speed train load were analyzed by both the full-size fatigue test and numerical simulation in commercial FEM (finite element method) software Ansys. Considering damage concrete, a concrete constitutive model with concept mode-II microcracks for was selected applied model. Based on this model, system established relative simulations conducted. Also, results verified full...
