The stability and reliability of braking system are essential factors for the safe operation high-speed trains. In proposed work, tribological properties a newly developed brake disc material namely BD-1 were studied considering thermal-mechanical effects, as well evolutions wear debris, particularly examined. also compared with an existing commercial BD-2 in text. Friction tests carried out on against pad (BP) to simulate real emergence conditions 350 km/h railway. coupling effects friction...
ABSTRACTHigh-speed train brake discs face severe service conditions and subsequently risk of material failure during emergency braking. Thermal fatigue cracking is a major concern leading to catastrophic disc regarded as primary bottleneck in rapid rail transportation. Our proposed work establishes numerical prediction model estimate thermal crack initiation propagation low-alloy steel. We used modified Cockcroft-Latham criterion property tests determine the critical value. Through...
Effective braking in high-speed trains is one of the major bottlenecks expediting technology and possibilities to improve speed. Although substantial progress has been made increase operating speed, perhaps, thermal fatigue cracking brake discs a primary constraint so far. Thermal cause disc failure trains, especially with speed 350 km/h or above. In this study, new material composition proposed for trains. A comprehensive investigation presented based on crack initiation propagation, along...
Laser cladding has emerged as a promising technique for custom-built fabrications, remanufacturing, and repair of metallic components. However, frequent melting solidification in the process cause inevitable residual stresses that often lead to geometric discrepancies deterioration end product. The accurate physical interpretation powder consolidation remains challenging. Thermomechanical simulation potential comprehend layer-by-layer additive subsequent part-scale implications....
The analytical method for slope stability analysis requires a collapse mechanism in advance. multi-staged is generally assumed to be overall failure, whereas this kind of may suffer from local failure. However, failure rarely reported the previous research slopes, which result an overestimate stability. To end, incorporated into first time, so as develop complete approach assess multi-stage slopes. modified pseudo-dynamic conducted properly account seismic effects. Thanks limit and strength...
Abstract Novel electromagnetic (EM) materials with adjustable EM properties are anticipated to fulfill the requirements of electronic communication, national defense, and aerospace fields. In this study, functional Ti 3 C 2 T x @Ni composite powders Ni content were successfully prepared using a facile electroless plating strategy. The parameters can be regulated by controlling in powders. As increases, values real imaginary parts complex permittivity @ y Ni/wax (y = 10 ~ 80) 2-18 GHz show...
Abstract To optimize the tempering process of 40Cr13VTi steel containing V and Ti, effect temperature on microstructure, precipitation, properties stainless has been studied. Optical microscope (OM), scanning electron microscopy (SEM), energy dispersive spectrometer (EDS) were used to analyze microstructure precipitates. Tensile, impact, hardness testing tests performed test mechanical martensitic steel. The research results indicate that as increase temperature, carbides precipitated...
In this paper, the failure mechanism of piston in pneumatic down hole (DTH) impactor has been studied. Failed microstructure analyzed using light optical microscopy (OM) and scanning electron microscope (SEM). Impact toughness test Rockwell hardness were conducted. Results showed following: a) The carburizing layer IQCT failed is mainly composed acicular martensite lower bainite after carburizing-tempering-isothermal quenching-cryogenic treatment-tempering (IQCT), there are collapses on...
