Validation of a Dynamic Simulation of a Five Degree of Freedom Point Contact Joint
(2007-11-05)A new special case computer simulation to model the non-linear, three dimensional dynamic equations of motion of a five degree of freedom point contact joint has been developed and the functionality has been validated with ... -
Validation of the Lattice Boltzmann Method for Direct Numerical Simulation of Wall-Bounded Turbulent Flows
(2011-09-18)In this work, the lattice Boltzmann method (LBM) was validated for direct numerical simulation (DNS) of wall-bounded turbulent flows. The LBM is a discrete-particle-based method that numerically solves the Boltzmann equation ... -
Vibroacoustic Analysis and Optimization of an Aft-Fuselage Mounted Twin-Engine Aircraft
Aft-fuselage mounted twin-engine style aircraft dominate the business jet industry. This aircraft provides a decreased transmission path for structure-borne engine vibrations when compared to wing-mounted aircraft found ... -
Vision-based Fault Detection in Assembly Automation
(2012-07-17)Production downtime caused by machine faults presents a major area of concern for the manufacturing industry and can especially impact the productivity of assembly systems. Traditional fault detection systems use a variety ... -
Visualization of Detonation Propagation in a Round Tube Equipped with Repeating Orifice Plates
This study used self-luminous high-speed photography to visualize quasi-detonation propagation and deflagration-to-detonation transition (DDT) in a transparent round tube equipped with repeating orifice plates. Experiments ... -
Vortex evolution in the wake of accelerating low-aspect-ratio plates and three-dimensional bodies of revolution
To find examples of effecient locomotion and manoeuvrability, one need only turn to the elegant solutions natural flyers and swimmers have converged upon. This dissertation is specifically motivated by processes of ... -
Wind Shear, Gust, and Yaw-Induced Dynamic Stall on Wind-Turbine Blades
(2016-05-31)This study examined the effect of a spanwise angle of attack gradient on the growth and stability of a dynamic stall vortex in a rotating system. It was found that a spanwise angle of attack gradient induces a corresponding ... -
Wing Kinematics and Flexibility for Optimal Manoeuvring and Escape
Understanding how animals control the dynamic stall vortices in their wake is critical to developing micro-aerial vehicles and autonomous underwater vehicles, not to mention wind turbines, delta wings, and rotor craft that ... -
Workspace Generation for Wire-Actuated Parallel Manipulators
(2009-10-20)This thesis focuses on the methods and results of the workspace formulation of wire-actuated parallel manipulators. Four methods of workspace generation are studied. The null space method, based on the calculation of wire ... -
Wrist Motion Simulation With a Rigid Body Spring Model Comparing Different Elements Modeling Approaches
(2016-04-08)A rigid body spring model was used to simulate wrist motions. The carpal bones were constructed based on a computed tomography of a cadaver wrist. Bony structures were assembled as a wrist model in the simulation software, ... -
Yielding Behaviour of Electron Beam Lithography and Focused Ion Beam Made Nanocrystalline Micro/Nanopillars
(2016-10-03)Electron beam lithography (EBL) and focused ion beam (FIB) methods were developed in house to fabricate nanocrystalline nickel micro/nanopillars so to compare the effect of fabrication on plastic yielding. EBL was used to ...
