The hydrogen circulation pump is one of the core components cycle system. To solve problem low density and possibility leakage, a vortex designed. Taking three-dimensional flow field as research object, CFD (computational fluid dynamics) numerical calculation model cavity was established, internal simulation performed to analyze performance characteristics at different speeds determine. investigate effects rates 80 L/min, 100 120 140 rotational r/min, number vanes 32, 36, 40 on circulating...
Uneven subgrade frost heave has been a severe problem for the operation of high-speed railways in cold regions. In order to reveal influencing mechanism on vehicle-track system, novel FEM (finite element method) model based an explicit algorithm was proposed. model, existence leverage effect slab track, which caused by heave, realistically reproduced at first, and then vehicle started running evaluating influence whole dynamic system. Results show that plays key role analyzing besides track...
Crack propagation produced by frost heave affects the durability of slab-track structures in high-humidity and cold regions China. This work is intended to reveal evolution laws frost-heave crack propagation, establish evaluation criteria for investigate factors involved propagation. Firstly, preparing specimens with initial cracks, an experiment was designed. The process carried out means digital image correlation (DIC) technology acoustic emission (AE) technology, respectively. These...
