COURSE OBJECTIVES

Upon completing this Random Vibe and Shock Testing Training course, learners will be able to meet these objectives:

  • How to plan, conduct and evaluate vibration and shock tests and screens.
  • How to attack vibration and noise problems.
  • How to make vibration isolation, damping, and absorbers work for vibration and noise control.
  • How noise is generated and radiated, and how it can be reduced.
CUSTOMIZE IT
  • We can adapt this Random Vibe and Shock Testing Training course to your group’s background and work requirements at little to no added cost.
  • If you are familiar with some aspects of this Random Vibe and Shock Testing course, we can omit or shorten their discussion.
  • We can adjust the emphasis placed on the various topics or build the Random Vibe and Shock Testing course around the mix of technologies of interest to you (including technologies other than those included in this outline).
  • If your background is nontechnical, we can exclude the more technical topics, include the topics that may be of special interest to you (e.g., as a manager or policy-maker), and present the Random Vibe and Shock course in a manner understandable to lay audiences.

COURSE SYLLABUS

  1. Minimal math review of basics of vibration, commencing with uniaxial and torsional SDoF systems. Resonance. Vibration control.
  2. 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.
  3. Extension of SDoF to the understanding of multi-resonant continuous systems encountered in land, sea, air, and space vehicle structures and cargo, as well as in electronic products. Random Vibe and Shock Testing Training
  4. Types of shakers — Tradeoffs between mechanical, electrohydraulic (servohydraulic), electrodynamic (electromagnetic), and piezoelectric shakers and systems. Limitations. Diagnostics.
  5. Sinusoidal one-frequency-at-a-time vibration testing — Interpreting sine test standards. Conducting tests.
  6. Random Vibration Testing — Broad-spectrum all-frequencies-at-once vibration testing. Interpreting random vibration test standards. Conducting tests.
  7. Simultaneous multi-axis testing gradually replaced the practice of reorienting devices under test (DUT) on single-axis shakers.
  8. Environmental stress screening of electronics production. Extensions to highly accelerated stress screening (HASS) and to highly accelerated life testing (HALT).
  9. Assisting designers to improve their designs by (a) substituting materials of greater damping or (b) adding damping or (c) avoiding “stacking” of resonances.
  10. Understanding automotive buzz, squeak, and rattle (BSR) — Assisting designers to solve BSR problems. Conducting BSR tests of materials and products.
  11. Intense noise (acoustic) testing of launch vehicles and spacecraft.
  12. 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.
  13. Shock response spectrum (SRS) for understanding the effects of shock on hardware. Use of SRS in evaluating shock test methods, in specifying shock tests, and in conducting shock tests.
  14. Attaching DUT via vibration and shock test fixtures — Large DUTs may require head expanders and/or slip plates.
  15. Modal testing — Assisting designers.
