The mechanism presented in this paper generates a partially negative stiffness characteristic, which is suitable for the balancing of a pendulum in a gravity field. The mechanism uses deformation in the axial direction of the base joint to store potential energy. The proposed design is located next to the base joint of the pendulum in an area...

The goal of the research described in this thesis was to investigate the basis of dissipation dilution as well as make it comprehensible. In the written literature we could find that the kinetic energy of an oscillating beam is stored into two types of potential energy~\cite{Kippenberg, Kotthaus}. A dissipative bending component and a...

In the past decades, great progress has been made in analyzing lateral torsional buckling of slender beams. The phenomena has been accurately described by differential equations, closed form solutions are available for specific cases and the solution for any load and any boundary condition can be obtained by finite element analysis. Timber and...

With the arrival of the Eurocode, the calculations regarding shear resistance, have become increasingly conservative compared to former concrete standards. For example in Voorschriften Beton 1974 (VB 74), a former concrete standard, a shear resistance combination of concrete, stirrups and prestress was allowed. Whereas the Eurocode assumes the...

Zeeland, located in the south west of The Netherlands, has suffered major casualties and damage due to the flood in 1953. After the disaster, the Dutch Government appointed the so-called Deltacomittee, provided with the task of advising on the execution of the Deltaplan. As part of the Deltaplan, North Sea estuaries has been closed off from the...

This thesis continues the work performed by Ferreira and Almeida on the topic of weight and cost reduction of composite multi-spar torsion-bending boxes. The goal is to find the influence of changes to the structural configuration on the resulting weight of said torsion-bending boxes. Using analytical methods, combined into the BoxSolver MATLAB...

Micro air vehicles (MAVs) are small aircraft that are promising for search and rescue missions or remote observations of hazardous or inaccessible areas. Currently one of the problems MAVs face is the limited action radius. To increase the action radius, a more energy efficient MAV is needed. This can be achieved by exploiting the resonance of...

Locking mechanisms are used in a wide range of applications including energy saving mechanisms in the field of robotics. In this thesis a new class of locking mechanisms is investigated: a combination between a singular- and a friction locking mechanism (singular-friction locker) which is statically balanced with one additional spring. This...

In dit Bachelor eindwerk is onderzoek gedaan naar de effectieve kiplengte van liggers met rechthoekige doorsneden. In een voorgaand eindwerk is hier al onderzoek naar gedaan door Roeland van Straten. Daarom zijn er bepaalde delen uit het desbetreffende onderzoek overgenomen ter ondersteuning van dit eindwerk. Het gaat hierbij om de paragrafen 1...

A gravity equilibrator is a statically balanced system which is designed to counterbalance a mass such that any preferred position is eliminated and thereby the required operating effort to move the mass is greatly reduced. Current spring-to-mass gravity equilibrators are limited in their range of motion as a result of design limitations. An...

Van Vliet, E. (author)
In skew bridges torsion occurs. This leads to a substantial amount of reinforcement stirrups. Minalu already did research to torsion in bridge decks with different types of finite element models. The question when torsion cracks will really occur is still unanswered. This question is the main subject of this research. The focus of the research...

Variable speed drives can cause components of any frequency known as interharmonics. Large variable speed drives in the order of tens of megawatts can replace Gas Turbines in driving cooling compressors in a Liquefied Natural Gas Plant. The drives used in this application are among the largest drives that are built today. As a consequence the...

For the geothermal wells of the Delft Aardwarmte Project it has been chosen to drill with glass-reinforced epoxy (GRE) composite casing in a drilling-with-casing setup. This MSc thesis report describes the results of experimental work to assess the stress-strain behaviour of GRE casing, in particular under axial, torsional and combined axial...

Rijff, B.L. (author)
A gravity balancer is a mechanism that compensates the weight of a mass over a range of motion. When no friction is present, this gives an energy efficient mechanism and little effort is required to move an object. Conventional mechanisms have drawbacks due to the use of conventional rigid joints. Compliant joints do not have these disadvantages...
