Abstract:

Rail surface defects are a serious concern for railway infrastructure managers all around the world. They lead to poor ride quality due to excess vibration and noise; in rare cases, they can result in a broken rail and a train derailment. Defects are typically classified as ‘rail studs’ when they initiate from the white etching layer, and ‘rail squats’ when they initiate from rolling contact fatigue. This paper presents a novel investigation into rail squat initiation and growth simulations using peridynamic theory. To the best of the authors’ knowledge, no other comprehensive study of rail sq

Abstract:

The transimpedance conversion circuit is an important part of the fluorescent optical fiber temperature sensor, which is used for rare earth fluorescence detection. Transimpedance conversion circuits can benefit from the wide input range, high gain, low input offset voltage, and high common-mode rejection ratio of rail-to-rail operational amplifiers. In this paper, a constant transconductance rail-to-rail operational amplifier is designed and implemented based on the 0.18 μm CMOS process. According to the simulation results, the transconductance change rate of the operational amplifier is 4.8%

Abstract:

Clean heavy rail steel was prepared by the process of vacuum induction furnace smelting, forge work and rolling. Effects of Rare earths (RE) on phase transformation and microstructure of heavy rail steel were investigated by thermal simulation machine, metallographic microscope and scanning electronic microscope. Thermal simulate tests indicate that, RE can move the C curve of pearlite transformation to lower right, prolong the incubation period of pearlite and improve the stability of undercooled austenite. The minimum incubation period of pearlite transformation is increased from 24s to 30s

Abstract:

Self-shielded flux-cored wire is a new type of welding material that has the advantages of outdoor and high-efficiency application, and it has been used widely for rail repair. A self-shielded flux-cored wire with high alkalinity and rare earth elements was taken for research, and the microstructure, inclusions, hardness and the impact toughness were studied. Rare earth elements could eliminate the oxygen and sulfur when they were added into the molten pool. The addition amount has been optimized to the range of 4% in the self-shielded flux-cored wire when used for rail repairing.

Abstract:

Rail discontinuities are one of the main sources of wheel impact causing high levels of noise, vibration and stresses in railway track. Even though various multi-body train–track interaction models have been developed in the past decade, accurate modeling and analysis of the track dynamic behavior in the vicinity of rail discontinuities is rare in the literature. In this paper, formulation of a new explicit multi-body dynamic (MBD) model incorporating detailed wagon, wheel–rail subsystems and track containing a rail discontinuity (rail joint) is reported.

Abstract:

Abstract The aluminothermic welding (ATW) process is the most commonly used welding process for welding rails (track) in the field. The large amount of weld metal added in the ATW process may result in a wide uneven surface zone on the rail head, which may, in rare cases, lead to irregularities in wear and plastic deformation due to high dynamic wheel-rail forces as wheels pass. The present paper studies the introduction of additional forging to the ATW process, intended to reduce the width of the zone affected by the heat input, while not creating a more detrimental residual stress field.

Abstract:

To study the effect of Ce on the morphology of manganese sulfide, we added different contents of Ce into U75V heavy rail steel. The composition and morphology of sulfide in steel were analyzed. The inclusions’ number, size, and aspect ratio were analyzed by automatic scanning electron microscope ASPEX. The results show that the inclusions in heavy rail steel without Ce are elongated MnS and irregular Al-Si-Ca-O inclusions. With the increase of Ce from 52 ppm to 340 ppm, the composition of main inclusions changes along the route of Ce2O2S-MnS → Ce2O2S-MnS-Ce2S3 → Ce2O2S-Ce3S4-Ce2S3 → Ce2O2S-Ce3

Such issues lend these assets to state ownership, especially in developing countries. State enterprises are fundamental to long-term health of the economy. Unfortunately, state enterprises are often marred by red

Abstract:

Pancreatic injuries include a variety of injuries from simple contusion to complete rupture of the duct and pancreatic head. Although pancreatic lesions are rare in children, the pancreatic pseudocyst is the most common posttraumatic cystic lesion of the pancreas and is a localized collection containing pancreatic juice and the peripancreatic necrotic test. The management of the pancreatic pseudocyst has evolved from the stage of exclusive surgical treatment exclusively, to the conservative one, respectively the stage of minimally invasive treatment (percutaneous drainage, endoscopic drainage)

This paper examines and discusses the dynamic response of a high-speed train-bridge-soil-pile foundation system to near-fault earthquakes. A 72 + 120 + 72 m continuous girder bridge of a high-speed railroad was selected as the model for calculation. Based on the p-y model for simulating pile-soil interaction, the moment-curvature analysis program XTRACT is used to calculate the moment and curvature of bridge piers and pile foundation sections, and the finite element (FE) software is used to establish two nonlinear global bridge models under seismic effects in the high-intensity zone, one consi

Abstract:

Purpose The purpose of this paper is to propose the complementary design rules, give a quantitative comparison and analyze the force production mechanism of two kinds of primary wound field flux-switching linear (PWFFSL) motors. Design/methodology/approach PWFFSL motors have the merits of no use of rare-earth magnet, low cost and a wide operation range in which the armature windings and the field windings are all located at the short primary mover and the secondary is very robust. Hence, the PWFFSL motor is ideal for rail transportation systems which need a long stator and a wide speed range.

Abstract:

The Ankeng Light Rail Metro System (ALRMS) is a Design-Build (DB) construction project located in New Taipei City. The Anhsin Bridge (AB) is one of the major parts of ALRMS. The original concept from the client, the Department of Rapid Transit Systems (DRTS), New Taipei City Government, was to design Anhsin Bridge as a steel arch bridge, which inevitably would require construction of some piers in the river reservation zone. Also, a temporary access bridge would be necessary during the erection of the steel frame. All these would pose a harmful situation for the river flow. Considering environ

Lew Martin's poetic turn, writing that: "[t]he raging fury of Edwardian ornamentation and enrichment fairly flickers in the sun," is a rare moment in New Zealand's too frequently prosaic architectural historical lexicon, but there is perhaps something in the stylistic frenzy of the early 1900s that results in the pleasure of architectural description, and adjectives of transition and movement. In their description of "Gingerbread" George Troup's 1906 Dunedin Railway Station, Stacpoole and Beaven asserted that the rich, boldness of the architecture and its physical illusion of grandness "is a c

Abstract:

Mg-Gd-Y-Zn-Mn (MVWZ842) is a kind of high rare earth magnesium alloy with high strength, high toughness and multi-scale strengthening mechanisms. After heat treatment, the maximum tensile strength of MVWZ842 alloy is more than 550 MPa, and the elongation is more than 5%. Because of its great mechanical properties, MVWZ842 has broad application potential in aerospace and rail transit. However, the addition of high rare earth elements makes the deformation resistance of MVWZ842 alloy increase to some extent. This leads to the difficulty of direct plastic processing forming and large structural p

During two dry season visits (July 1997, June 1998) to the lower Garanga River valley on the island of Isabel, we recorded 65 resident and 6 migrant species of birds. We document relative abundances, habitat preferences, and foraging guilds for the members of the bird community. The Garanga River site sustains all but 11 of the 76 species of landbirds known from Isabel. Of those 11 species, four are small-island or beach specialists, three are mon
