Design of a mobile robotic platform with variable footprint by alexander n wilhelm a thesis presented to the university of waterloo in fulfillment of the thesis requirement for the degree robot with seven universal wheels and a passive rocker-bogie suspension that can climb steps up to 150 mm, although it must align.
For a new design of bogie frame destined for a new type of application, all four- validation stages shall be used from the above it follows that comprehensive process of design and assessment of railway bogies thesis, university of london, department of mechanical engineering imperial college, london sw7, uk. Capacity as rocker-bogie in this thesis study, new bogie mechanism consisted of double-lambda mechanisms, which has been firstly presented by pafnuty lvovich chebyshev in 1869, is solved by analytically to define the positions and singular configurations a new structural synthesis formula also has. The analysis has confirmed that this type of bogie frame is very sensitive to torsion, which suggests that the twist loading case should be carefully investigated if an open-shaped bogie frame is involved in a particular bogie it is also shown that the potential failure of a new bogie frame may be ascertained at the design stage. Thesis submitted to the university of london for the degree of doctor of to put this research into context the thesis begins with an introduction to the vehicle- train design 61 how can track loading be reduced 62 light-weighting of rail vehicles 63 optimised yaw stiffness 64 steering bogies 641 steered or.

Bogie primary suspension master's thesis in the international master's programme applied mechanics employed to create a 50 dofs one car railway vehicle model with two bogies to verify the simulation the optimized values of design parameters (bogie primary suspension stiffness and damping) are found for each.
This msc thesis work is a part of my academic curriculum on rail vehicle engineering i am pursuing my master degree in vehicle engineering at the school of engineering sciences of kth royal institute of technology, stockholm i got the opportunity to conduct my thesis work at the institute of system. And stability which represents a key problem in the design of modern railway vehicles in modern rail vehicles, bogie design involves satisfying a stability constraint at maximum speed, at the same time prandi, d, “railway bogie stability control from secondary yaw actuators”, msc thesis, politecnico di milano , 2014.
Drives, have the largest potential of reducing the unsprung mass by an alternative vehicle design reducing the unsprung mass of a trailer bogie has a more limited potential and since the conceptual design of a bogie is thesis, department of applied mechanics, chalmers university of technology. This thesis continues the development of an intelligent sensing scheme using practical techniques for estimating the the independently rotating wheelset design (irw) de-couples the wheels losing the mechanical feedback derailment the suspension configuration varies depending on the bogie design, however. Nowadays, the mpl75 is over-motorized with four motor bogies due to its original design with four cars the mpl75 is composed of two motor bogies per motor car (four in all) and two carrier bogies a motor bogie contains two driving axles fitted with a differential and a central dc motor connected by elastic couplings then.

This thesis will focus primarily on the control of the individual vehicle this thesis will specifically present a controller for a suspended atn vehicle using a captive bogie design that tracks position and minimizes centripetal acceleration the general vehicle and system design is being referenced from work done by. Railway technology department of vehicle engineering royal institute of technology carbody and passengers in rail vehicle dynamics doctoral thesis by pelle carlbom working on this thesis i have made an effort to understand both this design allows yaw motions between carbody and bogie frame owing to. The aim of this thesis is to overcome the trade-off between stability in straight track and curving capability, that is a typical mechanical design limit of a passive railway vehicle in this sense, active control is here implemented as a controllable yaw torque between the two bogies and the carbody the idea, that has been.
