Finite Element Analysis of a Kite for Power Generation

The kite is modelled with the non-linear finite element method to stay close to its physical properties and represent its full non-linear flexible behaviour. The inflatable beams in the leading edge and struts are modelled with regular beam elements that represent the behaviour to reduce the amount of degrees of freedom drastically. The canopy...

Machines with high accuracy on factory floors

This thesis will propose a new method to predict the response of sensitive equipment, once it is installed on the factory floor. Currently, only the stiffness of the floor is taken into account when the dynamic response of a machine on a floor is predicted. To improve these methods, a short literature survey is done about the dynamics of factory...

Rider Control Identification in Bicycling

Following in the wake of the increased bicycle popularity, bicycle research arose in the late 19th century. Early research, regarding the dynamic behavior of an uncontrolled bicycle, resulted in the Carvallo (1899) and more general Whipple (1899) model. In the past years, extensive research has been done to validate these uncontrolled bicycle...

Impulse Based Substructuring: Theory, Improvement, and its Implementation on Real Problems

Dynamic substructuring as a method to solve complex systems is becoming very important. Dynamic substructuring techniques are based on assembling the dynamic models of some simpler structures in order to generate the dynamic model of a complex structure. Impulse Based Substructuring (IBS) as a time domain substructuring technique computes...

Abdominal Wall Vibration Analysis for Evaluation of Biomechanical Properties and Physiological Diagnosis of Internal Abdomen

The human abdominal cavity is an interesting part of the human body, containing a lot of important organs which, due to relative soft boundaries, are quite accessible for examination. Conditions like mechanical bowel obstruction, obstruction of the inferior vena cava, abnormalities of the viscera and existence of abdominal aortic aneurysms can...

Fundamental Theory and Implementation of the Wang-O'Gara-Tucker Model for the Modeling of Fiber Orientation in Fiber Filled Injection Molded Thermoplastics

The purpose of this master project is to implement the Wang-O'Gara-Tucker model to simulate the fiber orientation in fiber filled injection molded thermoplastics. A part of the extensive fundamental theory behind this model, and the implementations are treated in Part I of the thesis, the theory part. This part consists of the first eight...

Fluid Force Identification: Verifying and Validating a Method to Predict Wear of a Control Rod in a Nuclear Power Plant

In this thesis a method to model and identify the force inducing a vibration on the control rods of a nuclear power plant is verified, but could not be validated. The aim of the method is to be able to predict wear in future nuclear power plant designs. This study is based on a study by Bodel [1], and reviews, adjusts and extents its contents....

Model Reduction & Interface Modeling in Dynamic Substructuring: Application to a Multi-megawatt Wind Turbine

In modern day society concern is growing about the use of fossil fuels to meet our constantly rising energy demands, and the need for more sustainable energy is growing. Wind energy certainly has the potential to play a significant role in a sustainable future world energy supply and the wind power industry has grown to a globalized multi...

Feasibility study of a tire hydroplaning simulation in a finite element code using a coupled Eulerian-Lagrangian method

Feasibility study of a tire hydroplaning simulation in a finite element code using a coupled Eulerian-Lagrangian method. The considered FEA code is Simulia's Abaqus. Fundamentals of Abaqus' FSI solver is considered. This includes fluid and structure mechanics and fluid-structure interaction issues. The FSI solver is benchmarked. Conclusions and...
