Abstract:

The rate at which a railway track deteriorates depends on the response of the track under different static and repeated dynamic forces. These wheel/rail forces lead to imperfections in the rail surface and deviation in track geometry alignment. The wheel/rail forces are dependent upon the quality of maintenance of the characteristics of both train and track. If train components such as wheelsets and suspensions are maintained to a high standard, less dynamic forces are generated at the wheel/rail interface and less damage is caused over time. Therefore, the amount and cost

Abstract:

I många västeuropeiska länder har metoden för skogsavverkning ändrats från användning av motorsåg till ett mekaniserat skogsavverkningssystem känt som kortvirkesmetoden. Denna metod är baserad på en tvåmaskinslösning – en skördare som fäller, grenar och sågar träden enlig fördefinierade längder, och en skotare som transporterar stockarna till en lastplats för vidare transport till en bearbetningsanläggning. För att utveckla skogsmaskiner som är skonsammare för marken behövs en djupare förståelse av interaktionen mellan terrängen och dragfordonet. Huvudfokus i detta projekt ligger på bandgående

Abstract:

The topic of this dissertation was the use of distributed computing to improve the modeling of the interaction between passenger cars and trucks. The two main focus areas were the development of a methodology to combine microscopic traffic simulation programs with driving simulator programs, and the application of a prototype distributed traffic simulation to study the impact of the length of an impeding vehicle on passing behavior. The methodology was motivated by the need to provide an easier way to create calibrated traffic flows in driving simulations and to capture vehicle behavior with

Abstract:

Methods of predicting the dynamic forces are developed for the cases of vehicles negotiating vertical and lateral track irregularities. The bounds of validity of various models of the track are evaluated, from single degree of freedom, lumped parameter models to the case of a two layered beam on elastic foundation with a moving dynamic load. For the case of the lateral response of a vehicle negotiating a track switch, a finite element model of the track is also developed. The vehicle model developed for-the vertical case contains all the rigid body modes of a four axle vehicle for which primar

Gyroscopes can detect rotations around an arbitrary axis and as such can be used to detect critical rotations.This thesis work will present an algorithm for utilising the accelerometer and gyroscope in a smartphone to detect inciden

This thesis presents an investigation of the flow physics governing aerodynamic inter-action mechanisms relevant to Formula One racing cars, in particular the influence of the front wing on the car chassis flat underbody and diffuser. The research has taken a fundamental approach, with emphasis on identifying the fundamental mechanisms governing the interaction. Wake diagnostic techniques have been used to identify the major flow features of the front wing wake that are likely to influence the flat underbody and diffuser. Models have then been designed to simulate these various flow features.

Full text

Abstract:

This thesis examines the effect of vehicle dynamics on lateral deterioration of the track alignment. As rail traffic runs along a route, the forces imposed upon the track cause the ballast to settle, and hence the track geometry deteriorates. At a specified value of deterioration the track geometry needs to be restored by tamping or other methods. As the deterioration is mainly in the vertical direction, this aspect has been more widely studied and models have been developed to predict vertical track geometry deterioration. On the other hand, lateral track deterioration is not as well understo

Abstract:

Due to the demands of increasing population and environmental concerns, the high-speed train has become an important means of transportation in many countries. However, severe vibration induced by high-speed trains can occur when train speeds approach the speed of waves in the ground and track deflections can then become large. Consequently, the track and ground may no longer behave linearly. The aim of this work is to develop a three-dimensional model of vehicle/track/ground interaction in the time domain that can include the consideration of soil nonlinearity.

In this thesis a train-track-bridge interaction (TTBI) model is developed in order to study the dynamic amplification from track irregularities on railway bridges traversed by freight trains. These simulations are of great importance since rail freight transport is expected to increase in order to meet the climate goals. The shift of the freight industry is however not accomplished without complications, because of the heavier and more frequent transportation higher demand is put on the infrastructure supporting the railways.

The only commercially operating magnetically levitated (maglev) transport system in the world is the link between Birmingham International Airport and the National Exhibition Centre. Comparative financial analysis for this route showed that the construction costs for both wheeled and maglev systems were similar and that the cost of the guideway accounted for over 70% of the total. In part this was because the guideway was elevated; a likely requirement for any future urban system. A substantial reduction in installation costs for a system of this nature can only be achieved by the use of cheap

Although there are plans for HSR in many states including Florida, the United States, however, is still hesitant to develop its own HSR network.

Abstract:

The wheel-rail contact is at the core of all research related to vehicletrackinteraction. This tiny interface governs the dynamic performanceof rail vehicles through the forces it transmits and, like any high stressconcentration zone, it is subjected to serious damage phenomena. Thus,a clear understanding of the rolling contact between wheel and rail is keyto realistic vehicle dynamics simulation and damage analysis. In a multi-body dynamics simulation, the demanding contact problemshould be evaluated at about every millisecond for several wheel-rail pairs.Hence, a rigorous treatment of the co

Abstract:

The increased use of continuously welded rails in the railway systems makes it necessary to increase the control of the rail stresses to avoid instability and damages of the rails. Large stresses are especially prone to appear at discontinuities in the railway systems, such as bridges, due to the interaction between the track and the bridge. The interaction leads to increased horizontal forces in the rails due to the changed stiffness between the embankment and the bridge, temperature variations, bending of the bridge structure because of vertical traffic loads and braking and traction forces.

Abstract:

<p>Numerical procedures for reliable wheel and rail wearprediction are rare. Recent development of simulationtechniques and computer power together with tribologicalknowledge do however suggest computer aided wear prediction.The objective of the related research field at the RoyalInstitute of Technology (KTH) is to arrive at a numericalprocedure able to simulate profile evolution due to uniformwear to a degree of accuracy sufficient for application tovehicle dynamics simulation. Such a tool would be useful formaintenance planning as well as optimisation of the transportsystem and its component
