A Laser Plane Attitude Evaluation Method for Rail Profile Measurement Sensors [PDF]
Sensors, 2023 The non-coplanar lasers on both sides of the rail during full-section rail profile measurement based on line-structured light vision will cause the measured profile to be distorted, resulting in measurement errors. Currently, in the field of rail profile

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 ...
