1. Ultra-High Rotational Speed effects on Paperboard Textile Tubes

 

Proposal, development, and testing on a test machine capable of shaft drive or nip loading a textile tube up to 25,000 rpm. Results included a new product capable of meeting the ever higher customer standards.

 

2. Critical Speed (failure speed) of long (>2m) papermill cores

 

Proposal, development, and testing of long Papermill Cores for Harmonic Frequencies and Flexural Modulus (see standard test protocol T-148). Second test machine capable of spinning long cores to failure speed.

 

3. Improving the efficiencies of High speed doffing

 

Proposal, development, and testing of high speed textile tubes at multiple industrial locations using High Speed Video up to 10,000 frames per second. All applications resulted in efficiency increases.

 

4. Evaluating sources of failure at Extreme Pressures on film cores

 

Proposal, development of a loading machine, and testing of paper cores to radial pressures of over 1000 psi. Results included the development of better products and providing QA for customer products.

5. Reducing warpage due to High Humidity

 

Proposal, development of machine and test protocol, and testing of long cores for warpage sensitivity. Results included the elimination of an annual and widespread customer problem.

 

6. The Grand Unified Wear Model (GUWM)

 

Proposal, and development of test fixtures, protocols, and software to estimate high mileage tire wear from simple tire tread contact motion. Results were a weather map of tire tread wear.

 

7. The Hybrid Rubber Friction Model (HRFM)

 

Proposal, development of test protocol, software, and PhD Dissertation. A system which combined machine vision of loaded rubber blocks and finite element analysis to generate a hybrid rubber friction model for use in modeling of tires.

 

8. Mobile Vehicle Course Validation System

 

Proposal, development of electronics and test protocols, and testing on fleet vehicles used in tire wear testing. Software written to show an easy to read picture of errors. In use today for validation of vendor fleet accuracy.

 

9. High Incidence Angle Cascade Wind Tunnel

Researching and developing a specialized wind tunnel for measuring stalled air flow in Navy fighter plane engines. Tunnel capable of 240 1.5% kph airflow across a 0.3 m square test section.

 

10. Four Basic Acoustic Calibration Systems

 

The development of four identical acoustics laboratory fixtures to demonstrate various acoustics phenomena to senior mechanical engineering students. Also included leading the labs.
