Vibration Modeling and Experimental Analysis of a Locomotive Cab
(Virginia Tech, 1997-05-01)
This study evaluates noise and vibrations in a heavy freight locomotive cab, and
provides several measures for providing more comfort to the crew. A full-scale
production cab and sill structure is used to provide ...
Optimal Vehicle Path Generator Using Optimization Methods
(Virginia Tech, 1998-04-15)
This research explores the idea of developing an optimal
path generator that can be used in conjunction with a
feedback steering controller to automate track testing
experiment. This study specifically concentrates ...
An Experimental Evaluation of the Application of Smart Damping Materials for Reducing Structural Noise and Vibrations
(Virginia Tech, 1999-04-09)
This study evaluates the application of smart damping materials for reducing structural noise and vibrations. The primary purposes of this study are to:
1. Explore the feasibility of smart damping materials, such as ...
Experimentally-Based Analytical Prediction of Structural Vibration
(Virginia Tech, 1997-12-01)
This study evaluates the vibration isolation effect of various mounting systems in a heavy freight locomotive cab, and provides an analytical method for the prediction of structural vibration. The cab is set up in a ...
Statistical Characterization of Vehicle and Track Interaction Using Rail Vehicle Response and Track Geometry Measurements
(Virginia Tech, 1998-06-29)
This study evaluates the dynamic interaction between rail vehicles and the track on which they travel. The measurements were analyzed in the time and frequency domain. The effects of external parameters such as the vehicle ...
Experimental Evaluation of Semiactive Magneto-Rheological Suspensions for Passenger Vehicles
(Virginia Tech, 1998-05-26)
This study experimentally evaluates the dynamic response of a single vehicle suspension incorporating a magneto-rheological (MR) damper. A full-scale two-degree-of-freedom (2DOF) quarter-car test apparatus has been ...
NUCARS Modeling of a Freight Locomotive with Steerable Trucks
(Virginia Tech, 1997-05-20)
The rail dynamics modeling package NUCARS has been used extensively to model freight cars. We have found that it can also be used effectively to model freight locomotives.
This thesis discusses the development of a ...
The Analysis and Creation of Track Irregularities Using TRAKVU
(Virginia Tech, 1998-06-30)
The accuracy of the results from a rail vehicle dynamic model is dependent on the realism of the track input to the model. An important part of the track input is the irregularities that exist on actual track. This study ...
Experimental Evaluation of Semiactive Magnetorheological Primary Suspensions for Heavy Truck Applications
(Virginia Tech, 1998-09-07)
This study evaluates the performance of a semiactive magnetorheological primary suspension on a heavy truck application. A set of magnetorheological dampers is designed, fabricated, and characterized. The set of ...
Design of a decentralized model reference adaptive controller for a mobile robot
(Virginia Tech, 1996-12-13)
Control systems for robotic manipulators have been investigated for several years. The
difficulty in designing a controller for a robotic manipulator is due to the highly
nonlinear, time-varying dynamics. Closed-loop ...
