Dynamic Analysis of Wheel-Rail Interaction Stress Distribution for ENR Locomotives [PDF]
Port Said Engineering Research Journal, 2023 Egyptian rails have gotten worn as a result of a lack of upkeep and inadequate rail grinding. If the new locomotives are designed to work with standard tracks, they should be able to move more efficiently and safely on standard rails than worn ones that ...

Formation Mechanism of Metro Rail Corrugation Based on Wheel–Rail Stick–Slip Behaviors
Applied Sciences, 2021 Field investigation shows that most corrugations occur on the inner rail surface of curved tracks with a radius of less than 700 m. In order to explore the formation mechanism of metro corrugation, the relationship between wheel–rail stick–slip ...

A CMOS rail-to-rail linear VI-converter [PDF]
Proceedings of ISCAS'95 - International Symposium on Circuits and Systems, 2002 A linear CMOS VI-converter operating in strong inversion with a common-mode input range from the negative to the positive supply rail is presented. The circuit consists of three linear VI-converters based on the difference of squares principle. Two of these perform the actual V to I conversion, while the third changes the bias currents of the first two
