Novel New Modeling Procedure For Industrial Machinery With Nonlinear Connections, Steven Whitican
Novel New Modeling Procedure For Industrial Machinery With Nonlinear Connections, Steven Whitican
Dissertations, Master's Theses and Master's Reports
Given current timelines for rolling out production at volume, the ability to model portions of the production process is of paramount importance. To model production, high-fidelity models of production assets must be obtained. The production assets are comprised of linear and nonlinear structures. The linear structures are well understood and defined. Significant work has, and is, being done to understand the nonlinear components. This work focuses on developing and correlating a model of a nonlinear component. The component studied and modeled is a linear guide. Linear guides are bearings which facilitate translational motion of machine axes. An accurate model of …

Performance Of Hard Disk Drives In High Noise Environments, Trinoy Dutta
Dissertations, Master's Theses and Master's Reports
Digital information stored in rotational media, such as Hard Disk Drives (HDD) needs to be reliable and readily accessible. Various studies have been performed on the modal analysis of HDDs and the noise emitted during operation. Analysis performed by Siemens Corporation, IBM and Tyco Fire Protection Products show that HDDs are sensitive to noise. This report initially focusses on identifying the critical frequency ranges and the levels of noise where the performance of the drives reduces. A series of tests have been performed using pink noise at one-third octave frequency bands at sound pressure levels ranging from 80 dB to …
Test-Analysis Model Correlation And Calibration Of A Multi-Component Plastic Part, Steven P. Carter
Test-Analysis Model Correlation And Calibration Of A Multi-Component Plastic Part, Steven P. Carter
Dissertations, Master's Theses and Master's Reports - Open
The goal of this project is to learn the necessary steps to create a finite element model, which can accurately predict the dynamic response of a Kohler Engines Heavy Duty Air Cleaner (HDAC). This air cleaner is composed of three glass reinforced plastic components and two air filters. Several uncertainties arose in the finite element (FE) model due to the HDAC’s component material properties and assembly conditions. To help understand and mitigate these uncertainties, analytical and experimental modal models were created concurrently to perform a model correlation and calibration. Over the course of the project simple and practical methods were …
Reverse Engineering The Structural And Acoustic Behavior Of A Stradivari Violin, Michael A. Pyrkosz
Reverse Engineering The Structural And Acoustic Behavior Of A Stradivari Violin, Michael A. Pyrkosz
Dissertations, Master's Theses and Master's Reports - Open
There is a tremendous amount of mystery that surrounds the instruments of Antonio Stradivari. There have been many studies done in the past, but no one completely understands exactly how he made his instruments, or why they are still considered the best in the world. This project is designed to develop an engineering model of one of Stradivari's violins that will accurately simulate the structural and acoustic behavior of the instrument. It also hopes to shine some light on what makes the instruments of Stradivari unique when compared to other violins. It will focus on geometry and material properties, utilizing …
