CAD Apps for Core Courses in AE and ME Curricula: Bridge Funding 

Sponsor: The MathWorks, Inc.

Start Date: 1/01/16

End Date: 5/31/17

Abstract

The proposed work is essentially a bridge effort. The goal is to advance the work that was performed in the previous instructional grant, in preparation for an NSF grant that will broaden the impact of our work. The primary objective is to develop a design tool that can be used with each of the five CAD apps and support further instructional software testing and assessment. Currently, when using any one of the apps, the user selects nodes, connects them to create a structure, applies boundary conditions, then applies loads, and finally runs the program after which results are displayed in different forms (movies, static drawings, tabular  data, pop‐ups, etc). The user essentially runs one case.

Computational Simulation of the Joint Expeditionary Collective Protection (JECP) System

Sponsor: Defense Threat Reduction Agency (DTRA)

Start Date: 6/24/08

End Date: 6/24/13

Abstract

This project will develop a computational fluid dynamics method for simulating ingress / egess into collective protection equipment being developed for the Joint Expeditionary Collective Protection program. The method will incorporate digital animation technology to replicate mission-specific human activity, will link with urban airflow models to provide external environmental conditions, and will utilize fabric-response structural models to simulate the effects of semi-rigid or flexible entryways.

LAT - Live Axis Turning

Sponsor: National Science Foundation (NSF)

Start Date: 4/01/06

End Date: 9/30/09

Abstract

The goal of this proposal is to develop a new method to create Non-Rotationally Symmetric (NRS) surfaces that overcomes the limitations of the current techniques and is fast, accurate and inexpensive. Diamond turning (DT) has revolutionized the fabrication of lightweight optical surfaces for defense and science applications such as forward-looking infrared radar and infrared spectrometers. It has made this impact not only because it can accurately and rapidly fabricate diffractive, refractive and reflective optical surfaces, but because it can create reference features tied to the optical surfaces to guarantee optical alignment. An emerging trend in optical design is the use of NRS surfaces that reduce complexity, bulk and weight. To create these surfaces, DT machines have been modified with a low-amplitude Fast Tool Servo, a third axis or a fly-cutter. The problem with the FTS is its limited range and the other techniques are plagued by thermal drift during long fabrication times. The proposed Live Axis Turning (LAT) process combines evolving technologies of air bearings, linear motors, high-resolution encoders and high-speed control systems into a moving lightweight toolpost on a conventional DT machine. The result is a more flexible machine that can increase production and reduce cost for NRS components.

Abstract

The Ninth Pan American Congress of Applied Mechanics (PACAM IX) will be held January 2-6, 2006, in Merida, Mexico. The Universidad Nacional Autónoma de México (UNAM) will be the host institution for this, the ninth biennial PACAM conference. The first PACAM was held in 1989 at the Catholic University of Rio de Janeiro. Subsequent PACAMs were held in Valparaiso, Chile, 1991, São Paulo, Bra¬zil, 1993, Buenos Aires, Argentina, 1995, San Juan, Puerto Rico, 1997, Rio de Janeiro, Brazil, 1999, Temuco Chile, 2002, and Havana, Cuba, 2004. The consensus is that these meetings provided outstanding venues for enhancing communication among the engineering scholarly communities of the Americas. The event will be sponsored by The American Academy of Mechanics as usual, and by The Mexican Academy of Engineering. In past PACAMs the primary deterrent to the success of the conferences was the high-cost of U.S. participants to travel to South America. For the upcoming PACAM IX, the proximity of Mexico to the U.S. mainland will enable relatively inexpensive travel for U.S. participants but will threaten Latin American participation. Therefore, the requested AFOSR support to subsidize attendance by scholars from outside the U.S. is critical. The consensus is that PACAM IX will foster, in the spirit of NAFTA, hemispheric cooperation and enhance the appropriate hemispheric leadership role of the U.S. in engineering and specifically, applied mechanics.
