Modeling Simulation and Preliminary Experimentation on Towed Tether System

Kolla, Pradeep (2007-12-15)

Aero-dynamic drag forces and their effect on the path taken by a cable in a towed system are studied with the aid of an advanced computational software packages. A piece of rope (tether) is towed at the top end in a ...

Modeling, Machine Vision Sensing and Material Flow System Definition of Braiding Point Motion

Ma, Guangli (2011-02-03)

This dissertation is focused on the modeling of one kind of braiding machine and its key part, the carrier. The carrier is a small mass-spring-damping tensioning system, which defines the characteristics and response of ...

On the Design, Synthesis, and Radiation Effect Prevention of a 6U Deep Space CubeSat

Halvorson, Michael (2020-11-24)

The Alabama Space Grant Consortium initiated a workforce development program across seven universities to build a 6U CubeSat with an astrophysics payload. The science mission, an investigation on the efficacy of augmented ...

Roll & Bank Estimation Using GPS/INS and Suspension Deflections

Brown, Lowell (2012-07-25)

This thesis presents three methods that provide and estimate of road bank by decoupling the vehicle roll due to dynamics and roll due road bank. Suspension deflection measurements were used to provide a measurement of the ...

Some Studies on Modeling and Simulation of a Disc Brake System for Squeal Prediction

Ahuja, Nitesh (2006-08-15)

Most mechanical systems that involve a sliding contact experience some degree of friction induced self-excited vibration. A well known example is brake squeal which is a top concern for automotive companies, who must spend ...

Statistical Model for Prediction of Life-Reduction in SAC Lead-free Interconnects during Long-Term High Temperature Storage using Principal Component Regression and Ridge Regression

Duraisamy, Sree Mitun (2016-05-18)

Electronics in military and defense applications may be stored for prolonged period of time prior to deployment in mission critical applications. In addition, electronics in automotive applications may be used underhood, ...

A Study of Lateral and Longitudinal Tire Forces Produced on a Deformable Surface with Applied Traction and Braking

McIntyre, David Michael (2015-05-11)

An investigation into the effects that changing tire characteristics have on the production of lateral and longitudinal tire forces was conducted on a test wheel that was subjected to external traction and braking forces. ...

Terminal Ballistics of Composite Panels and Verification of Finite Element Analysis

Grupp, Jonathan (2011-07-29)

Composite materials are becoming more prevalent in a wider range of applications due to the inherent advantages afforded by their strength to weight ratio over more traditional engineering materials such as metals. As such, ...

Tire Force Estimation in Off-Road Vehicles Using Suspension Strain and Deflection Measurements

Hill, Ryan (2012-01-24)

This thesis develops and analyzes the improvement of tire force estimation and analysis using strain gauge sensors and displacement sensors mounted on the suspension of an all-terrain vehicle. Vehicle dynamic models are ...

Ues of Vision Sensors and Lane Maps to Aid GPS-INS Navigation

Allen, John, Jr. (2011-08-25)

This thesis proposes a method to increase observability of a GPS/INS system operating under limited satellite coverage. Measurements from vision sensors are used to supplement the GPS pseudorange and pseudorange-rate ...

Use of Surface Specific Flow Factors in a Multi-Physical Model of Power Cylinder Components

Locker IV, Alex (2018-04-23)

New technologies are being introduced for power cylinder components at a faster rate due to the drive for better fuel economy and CO2 foot print reduction. This includes new and advanced coatings, materials, and surface ...

Variable-Stiffness Protective Material

Petersen, Caleb (2016-05-04)

The focus of this research is to develop a system for limiting the motion of a mechanical joint to prevent damage to the joint. One obvious application is enhancing the safety of human joints during athletic events. For ...
