Electromechanical Design and Development of the Virginia Tech Roller Rig Testing Facility for Wheel-rail Contact Mechanics and Dynamics
(Virginia Tech, 2016-09-28)
The electromechanical design and development of a sophisticated roller rig testing facility at the Railway Technologies Laboratory (RTL) of Virginia Polytechnic and State University (VT) is presented. The VT Roller Rig is ...
Simulation and Testing of Wave-Adaptive Modular Vessels
(Virginia Tech, 2014-01-20)
This study provides a comprehensive performance analysis of Wave-Adaptive Modular Vessels (WAM-V) using simulations and testing data. WAM-Vs are a new class of marine technology that build upon the advantages of lightweight, ...
Quantitative Laser-based Assessment of Top of Rail Friction Modifiers for Railroad Application
(Virginia Tech, 2016-05-04)
The primary purpose of this study is to assess the effectiveness and utility of laser-based sensors for measuring, quantitatively, the presence and extent of top-of-rail (TOR) friction modifiers that are commonly used in ...
The Application of Doppler LIDAR Technology for Rail Inspection and Track Geometry Assessment
(Virginia Tech, 2016-05-17)
The ability of a Doppler LIDAR (Light Detection and Ranging) system to measure the speed of a moving rail vehicle in a non-contacting manner is extended to capture the lateral and vertical irregularities of the track itself ...
Application of Multifunctional Doppler LIDAR for Non-contact Track Speed, Distance, and Curvature Assessment
(Virginia Tech, 2015-12-08)
The primary focus of this research is evaluation of feasibility, applicability, and accuracy of Doppler Light Detection And Ranging (LIDAR) sensors as non-contact means for measuring track speed, distance traveled, and ...
State of the Art Roller Rig for Precise Evaluation of Wheel-Rail Contact Mechanics and Dynamics
(Virginia Tech, 2016-01-25)
The focus of this study is on the development of a state-of-the-art single-wheel roller rig for studying contact mechanics and dynamics in railroad applications. The use of indoor-based simulation tools has become a mainstay ...
