Kinematic analysis of cam profiles used in compound bows
(University of Missouri--Columbia, 2009)
for an eccentric-circular cam design and a one-cam one-pulley design. By iteratively determining the bow limb, cam, and cable positions a relationship between the drawn length and drawn force will produce a draw-force curve. In fact, this curve represents...
Investigation of static interfacial fracture in orthotropic-orthotropic composite bimaterials using photoelasticity
(University of Missouri--Columbia, 2009)
The effects of static Mode I (opening mode) and mixed-mode (both Mode I - opening mode and Mode II - shear mode present) loading on orthotropic-orthotropic bimaterial interface cracks and isotropic-orthotropic bimaterial ...
Semi-analytical terminal and automatic approach and landing trajectory planners for unpowered reusable launch vehicle
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] A new guidance scheme for the terminal area energy management (TAEM) phase of an unpowered reusable launch vehicle (RLV) has been developed. The main ...
Nonlinear mechanics and testing of highly flexible one-dimensional structures using a camera-based motion analysis system
(University of Missouri--Columbia, 2006)
Both experimental and theoretical investigations are conducted for the dynamics of cables and strings. The exact equations of motion for finite but small amplitude vibration of string were derived based on a fully nonlinear ...
System modeling and control design of a two-stage metering poppet-valve system
(University of Missouri--Columbia, 2006)
control methods that comprise modified PI control, LQG control, H [mobius] control, and nonlinear feedback control are used to make a closed-loop poppet system. The nonlinear controller is only applied to the nonlinear system and certified by Lyapunov...
Sensitivity analysis and optimal design of conventional and magnnetorheological fluid brakes
(University of Missouri--Columbia, 2018)
Mechanical and electrical brakes have dominated the braking industry for many years and will most likely continue to do so for the foreseeable future due to their low cost and adequate operating performance, wide range of ...
X-ray topography techniques for the analysis of laser irradiated silicon
(University of Missouri--Columbia, 2005)
There is currently much interest in femtosecond scale laser interactions with materials. Comparison of the damage produced by the femtosecond laser pulses to the longer laser pulses is also of interest. This study examined ...
Theoretical analysis of heat and mass transfer processes in an evaporative cooling system with zeolite desiccant powered by solar energy
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Concerns about energy sources depletion and environmental pollution issues have been raised and is a top priority of the global community. Refrigeration ...
Air-side heat transfer enhancement by self-agitators
(University of Missouri--Columbia, 2019)
Airfoil-based self-agitators (AFAs), bio-inspired rectangular-shaped self-agitators (RSAs), and caudal-fin inspired hourglass-shaped self-agitators (CHSAs) were installed inside plate-fin heat exchanger. The heat transfer ...
Torque ripple attenuation for an axial piston swash plate type hydrostatic pump: noise considerations
(University of Missouri--Columbia, 2006)
The main goal of this work is to reduce the disturbing noise generated by axial piston swash plate type hydrostatic pumps by attenuating the shaft torque variation. The analysis begins by deriving the equation of the shaft ...
Modeling the inertial torque imbalance and foundation forces within an inline internal combustion engine : quantifying the equivalent mass approximation
(University of Missouri--Columbia, 2018)
single-piston engine. The next largest foundation forces are exhibited by a 2-piston engine, followed by a 3e-piston engine, and that a dramatic reduction in the foundation forces and torque imbalance may be obtained by using 4 or more pistons...
Experimental and analytical study on two-phase impingement cooling with and without electric field
(University of Missouri--Columbia, 2007)
Among the thermal management solutions for power electronics, two-phase jet or spray impingement cooling are two promising candidates. In this study, electrohydrodynamic atomization (EHDA) method is used to generate spray ...
Thermal-mechanical analysis of targets for high volume production of molybdenum-99 using low-enriched uranium
