ATI's Fundamentals of Random Vibration & Shock Testing course

Share |

Summary:

Technical Training Short On Site Course Quote

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:

    Steve Brenner Steve Brenner has been working in the field of environmental simulation and reliability testing for over 30 years.

    Beginning in the late sixties with reliability and design verification testing on the Lunar Module, the Space Shuttle in the eighties, to semiconductor manufacturing equipment in the nineties, Mr. Brenner has always been involved with the latest techniques for verifying equipment integrity through testing.

    Mr. Brenner began his career as an Environmental test engineer with Grumman Aerospace Corporation in New York, worked as design verification and reliability engineer for the Air Force, an Environmental Test Engineer for Lockheed Missiles and Space company, and spent 18 years with Kaiser Electronics in San Jose, where he managed the Environmental Test Lab and was involved with the design of hardware intended for severe environments.

    Mr. Brenner has been working as a consultant in the reliability testing field since 1996.

What you will learn:

  • 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.

    From this course you will obtain the ability to understand and communicate meaningfully with test personnel, perform basic engineering calculations and evaluate tradeoffs between test equipments' and procedures.

Course Outline:

  1. Minimal math review of basics of vibration, commencing with uniaxial and orsional 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 understanding of multi-resonant continuous systems encountered in land, sea, air and space vehicle structures and cargo, as well as in electronic products.

  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 replacing practice of reorienting device 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 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.
