This paper proposes a hybrid sensorless control strategy for rail transit application employing interior permanent magnet synchronous machine (IPMSM), which works under low
Tram manufacturers have different ways of approaching the design of low-floor trams with compact and reliable running gears, and therefore several tram architectures can still be found. A
Terminal capacity and performance have become a major concern for rail transit agencies in China due to the ever increasing passenger demand.

To study the cascading failure in real-world urban rail transit network, the cascading failure model is proposed by considering two essential
One was the development and commercial introduction of a new type of proprietary tapered steel pipe called the Tapertube (TM). It was developed primarily to provide commercial competition to the long
The research is based on similar work conducted for freight rail-roads, modified, as necessary, for the transit operating environment. The results should be of interest to engineers involved in the design,
This study aims to elucidate the effect of differences in just these two types of pinion bearings on the performance of gear units and thereby verify the applicability of cylindrical roller
The Transportation Technology Center Inc. (TTCI) developed TADSTMTM to monitor aring health through ac ngs as the train passes thro wlers” due to the low frequency the large spa component
Most Construction Engineering Groups designing New Rail Transit Systems require some type of Design Criteria REFERENCES but do not generally have O&M Staff familiar with Special Trackwork
The major objective of this research is to estimate the effects of temperature on tapered roller bearings through the investigation of strain and thermal behaviors. Autodesk Fusion 360 is
This research introduced novel mesh-type and mesh-type high-damping rail pads (NMTRP and MTHDRP) to mitigate RP''s stress and enhance damping efficiency while optimizing
Based on this Heavy Rail Transit Vehicle Turnout Speed Restriction, all future Metro RED Line #10 turnouts were adjusted to operate at only Cab Speed Codes of 9 mph and a New Metro Custom 645
SKF offers a range of tapered roller bearings for various applications, providing high stiffness and accommodating combined loads.
To investigate the use of ML to predict transit delays with these data, we compare the performance of the most adopted ML models for predicting transit delays. The aim is to
In this paper, we have proposed a model and problem formulation for estimating turnback capacity and delay at a rail transit terminal with two-tail tracks and considered the capacity evaluation
Comparative studies of composite materials for railway track applications are reviewed and presented in order to improve material
Optimization of group delay respon se of (apodized) tapered fiber Bragg grating by shaping taper t ransition and apodization window Konrad
Abstract This work studies the flexible rolling stock strategy in urban rail transit lines, by which various train units can be coupled to or uncoupled from the trains in certain stations according
Tapered roller bearing units Passenger rail bearings for extended service intervals In the passenger rail industry, finding solutions that are highly reliable is top of the agenda. Failures are costly, both in
10.1 The Upgraded Class “E” CTRBs” shall be guaranteed for satisfactory performance for a period of 48 months after supply or 36 months after putting in

7.1 The Upgraded Class “E” CTRB must be offered by bearing manufacturer having unconditional AAR approval for CTRB Class “E” running on worldwide railway
However, which type of femoral stem is superior remains controversial. The purpose of this study was to assess the clinical and radiographic outcomes of modular and nonmodular tapered
The new SKF Tapered roller bearings are improved to endure the stress in railway gearboxes for demanding applications. More robust cages, high-strength materials, and design optimizations
In this study, the measured track impact factor induced by the wheel–rail contact impact force of each test section (two continuous welded rails
This paper investigates a tapered bonded joint that was proposed to reduce the high stresses that can result in the more typical butt-strap joint configuration. The first type of analysis models the rails and
