Wayne Tustin’s training and consulting (licensed Professional Engineer in the State of California) interests lie in the environments that can lessen equipment availability, that can cause equipment downtime. His particular concerns: dynamics, primarily the measurement, analysis and simulation (in environmental testing laboratories) of mechanical shock and vibration (particularly random vibration), also the stimulation of latent defects during new product development and as a final step in production, also acoustic noise, as in quieting products and in automotive “buzz, squeak and rattle” testing.
Wayne’s explanations benefit not only test and development personnel (laboratory managers, test engineers, technicians and aides as well as designers) but also people from product quality, reliability and instrumentation whose activities require them to measure in-service dynamic events, generate and/or interpret test specifications and evaluate laboratory capabilities, testing machines and techniques. Many of these workers need simple working explanations of such subjects as random vibration.
Wayne’s first experience with dynamics was 1948-53 at Boeing Co. in Seattle, where in 1944 he had earned his BSEE degree from the University of Washington. From 1954-61 he managed field service and technical training at MB Electronics, then the leading USA manufacturer of vibration test equipment. Since 1962 he has supplied technical training to Government and Industry, and has taught in the USA and abroad (Australia, Canada, Denmark, Germany, Great Britain, Holland, Italy, Singapore, South Africa and Sweden). He is happy to propose customized onsite teaching.

Wayne will sample, in 3 hours, his 3-day course. In the 3 hours, he will introduce the concept of resonant behavior of a wide range of structures (the Tacoma Narrows Bridge down to electronic circuit boards). Laboratory vibration tests on samples determine whether product design and manufacture have avoided or at least lessened resonant responses. Wayne will introduce sinusoidal as well as random vibration test standards. He will show, by slides and video clips, how we perform those standard tests by means of (1.) EH or electrohydraulic or servohydraulic shaker systems and (2.) ED or electrodynamic shaker systems, including their power amplifiers and their controllers.
How does in-service vibr damage hardware? Animation of card flexing; show chip with damaged ball grid. Why is such weakness important to QE?
How do we measure in-service vibr? Why re such measurements important to QE?
Seismic & Land vehicles & Ships will use on-board accelerometer sensors & recorders; explain what accelerometer is, where place, how electrical signal is on-board recorded for later study, data becomes test spec.
Air vehicles on-board accelerometer sensors & telemetry much the same but record to higher frequencies and telemeter signals to ground for recording, study & becomes test spec.
