ATI's Vibration & Shock Measurement and Testing course
|
|
Summary:
This three-day course is primarily designed for test personnel who conduct or supervise or "contract out" vibration and shock tests. It also benefits design, quality and reliability specialists who interface with vibration and shock test activities.
Each student receives the instructor's brand
new, minimal-mathematics, minimal-theory
hardbound text Random Vibration & Shock
Testing, Measurement, Analysis & Calibration.
This 444 page, 4-color book also includes a CDROM
with video clips and animations.
Instructor:
Wayne Tustin has since 1995 been president of Equipment Reliability Institute (ERI),
a specialized engineering school and consultancy he founded in Santa Barbara, CA.
His BSEE degree is from the University of Washington, Seattle. He is a licensed Professional
Engineer - Quality in the State of California. Wayne's first encounter with vibration was
at Boeing/Seattle, performing what later came to be called modal tests, on the XB-52 prototype
of that highly reliable platform. Subsequently he headed field service and technical training
for a manufacturer of electrodynamic shakers, before establishing another specialized school
on which he left his name. Wayne has written several books and literally hundreds of articles
dealing with practical aspects of vibration and shock measurement and testing.
What you will learn:
Course Outline:
- Minimal math review of basics of vibration, commencing with uniaxial and orsional SDoF systems. Resonance. Vibration control.
- Instrumentation — How to select and correctly use displacement, velocity
and especially acceleration and force sensors and microphones. Minimizing
mechanical and electrical errors. Sensor and system dynamic calibration.
- Extension of SDoF to understanding of multi-resonant continuous systems
encountered in land, sea, air and space vehicle structures and cargo, as well as in
electronic products.
- Types of shakers — Tradeoffs between mechanical, electrohydraulic
(servohydraulic), electrodynamic (electromagnetic) and piezoelectric
shakers and systems. Limitations. Diagnostics.
- Sinusoidal one-frequency-at-a-time vibration testing — Interpreting sine test standards.
Conducting tests.
- Random Vibration Testing — Broad-spectrum all-frequencies-at-once vibration testing. Interpreting random vibration test standards. Conducting tests.
- Simultaneous multi-axis testing gradually replacing practice of reorienting device under test (DUT) on single-axis shakers.
- Environmental stress screening of electronics production. Extensions to highly accelerated stress screening (HASS) and to highly accelerated life testing (HALT).
- Assisting designers to improve their designs by (a) substituting materials of greater damping or (b) adding damping or (c) avoiding "stacking" of resonances.
- Understanding automotive buzz, squeak and rattle (BSR) — Assisting designers to solve BSR problems. Conducting BSR tests of materials and products.
- Intense noise (acoustic) testing of launch vehicles and spacecraft.
- Shock testing — Transportation testing. Pyroshock testing. Misuse of classical shock pulses on shock test machines and on shakers. More
realistic oscillatory shock testing on shakers.
- Shock response spectrum (SRS) for understanding effects of shock on hardware. Use of SRS in evaluating shock test methods, in specifying shock tests and in conducting shock tests.
- Attaching DUT via vibration and shock test fixtures — Large DUTs may require head expanders and/or slip plates.
- Modal testing — Assisting designers.
