Abstract:

Energy efficiency of haulage, in the production of mineral ores, was investigated through measurement of the rolling resistance experienced by haul trucks while traversing unsealed, unbound granular pavements. It appears pavement surface condition influences rolling resistance more significantly than pavement structural capacity. Validation of various modelling methods with in-situ pavement deflection measurements showed that simple methods are able to estimate pavement surface deflection with similar accuracy to more complex techniques, such as Finite Element Analysis.

The thesis reviews and studies current evaluation mechanisms, techniques and machines for testing rolling contact fatigue failure resistance and load capacity of coated components. The thesis investigates both normal and accelerated rolling contact fatigue evaluation test mechanisms and their models, and evaluation test technique principles suitable to the appraisal of coated bearing components. A major contribution of the thesis is the design and development of a new rolling contact fatigue evaluation test machine for coated components. Tests of the rolling contact fatigue of coated bearing r

Abstract:

The demands placed on back-up rolls in hot strip mills have been investigated by a combination of literature and industrial studies. The tribological operating conditions have been established and the maximum local loads and pressure distributions at the work roll/back-up roll interface have been obtained by processing mill and roll schedule data using a computer program (commercial software developed by V AI Industries (UK) Ltd) and applying the theories of contact mechanics. After a study of the responses of the rolls to these demands and possible failure mechanisms, research has centred on

Fordonsindustrin går mot alltmer autonoma fordon. Funktioner för fordonsreglering och förarstöd blir allt viktigare för att minska bränsleförbrukningen och förbättra förarupplevelsen. Med information om körmotståndets olika delar kan mer detaljerad information utnyttjas av funktioner som reglerar fordonen och deras prestanda kan därmed förbättras. Körmotståndet kan delas in i rullmotstånd, luftmotstånd samt förändring i potentiell energi orsakad av väglutning.

Abstract:

We consider first the single-track bicycle model and state relations between the tires’ lateral forces and the turning radius. From the tire model, a relation between the lateral forces and slip angles is obtained. The extra rolling resistance forces from cornering are by linear approximation obtained as a function of the slip angles. The bicycle model is validated against the Magic-formula tire model from Adams. The bicycle model is then applied on an optimization problem, where the optimal velocity for a track for some given test cases is determined such that the energy loss is as small as p

Abstract:

A large portion of the world’s total emissions is caused by the transport sector where rolling resistance is one of the contributing factors. The inner tyre temperature is a factor that greatly influences the rolling resistance. The effect of temperature and rolling resistance is often examined in standardised tests carried out in a lab environment. In this work, field tests were carried to find out typical operating temperatures in real driving scenarios. The field tests were carried out on one set of A-class tyres and one set of B-class tyres at different speeds: city-, small country road-,

Tire testing has been one of the important aspects of the tire industry because it helps identify the tire behavior which further helps in improving the design of tires. It also helps automotive manufacturers choose the best tire for their automobiles. Indoor tire testing helps in relating the data better because of greater repeatability of the testing setup as compared to outdoor testing. This study focusses on modifying a rolling resistance machine to make it capable of force and moment and cleat testing along with the standard rolling resistance test.

Abstract:

An operating vehicle requires energy to oppose the subjected driving resistances. This energy is supplied via the fuel combustion in the engine. Decreasing the opposing driving resistances for an operating vehicle increases its fuel efficiency: an effect which is highly valued in today’s industry, both from an environmental and economical point of view. Therefore a lot of progress has been made during recent years in the area of fuel efficient vehicles, even though some driving resistances still rises perplexity. These resistances are the air drag Fd generated by the viscous air opposing the v

In Sweden fall-related injuries among the elderly lead to over a thousand deaths and close to 300.0000 hospital visitations annually. Fall related injuries can in many cases lead to serious head injuries along with other fractures. The elderly are more prone to fall and sustain an injury because of conditions such as osteoporosis and weak muscles. Researchers at KTH from the Division of Neuronic Engineering have developed a special floor that absorbs energy from an impact which can reduce the severity of injury when a person falls. There has been research done on the floor focusing on hip frac

Abstract:

Pile foundations for bridges must often resist lateral loads produced by earthquakes and thermal expansion and contraction of the superstructure. Right-of-way constraints near bridge abutments are leading to an increased use of mechanically stabilized earth (MSE) walls below the abutment. Previous research has shown that lateral pile resistance can be greatly reduced when piles are placed close to MSE walls but design codes do not address this issue. A full-scale MSE wall was constructed and 24 lateral load tests were conducted on pipe, square and H piles spaced at distances of about 2 to 5 pi

碩士<br>國立成功大學<br>工程科學系<br>88<br>First in this thesis, it classifies pneumatic tires according to it’s structure, introducing the basic structure, the function and the quality of every material. And then it classifies according to the size and pattern. Last it explains the state of tires under every different kind of external force. The primary materials of tires are rubber and cord ply. Among them rubber is an incompressible, hyperelastic material and it’s stress-strain curve is nonlinear. So the mechanics behavior is explained with hyperelastic theorem. And the cord ply is taken th

In this research, the nonlinear Finite Element Method is introduced to comprehend mechanical properties of tires, such as the material properties and energy dissipation, in order to identify the source of the rolling resistance. In this research, both the 205/55R16 slick tires and pattern tires are investigate using the finite element program Abaqus. T

碩士<br>國立臺灣海洋大學<br>系統工程暨造船學系<br>99<br>This paper first introduce the each part of the tire, and describe the material property and function of each part of the tire. Then presented the meanings of code on the tire, the mechanical properties of the tires, and then discuss the mechanism of the occurrence of rolling resistance. The prime material of tire are rubber and ply, for rubber, its property can be describe by hyperelastic and viscoelastic, and the properties of ply layers can be modeled with rebar element. For finite element simulation, finite element software(ABAQUS) was used to bui
