A Two Day Foundation Course for Vibration Test Engineers and Technicians
On your site, customised to your requirements.

COURSE DESCRIPTION

This two day course provides a practical introduction to the subject of vibration testing. Designed around the needs of engineers new to the subject of vibration testing and yet offering a useful refresher course for more experienced users, this course explains how to interpret vibration test specifications and apply them to a vibration test system. Subjects covered are sinusoidal vibration, random vibration, and shock / bump testing together with a background to the equipment required for each type of test, methods of control and simple fixturing.

The course puts an emphasis on practical aspects of vibration testing culminating in the opportunity for every delegate to set up and run a complete vibration test on your system.

COURSE TOPIC SUMMARY

System limitations, Dynamic mass, Isolated systems, Cross-axial and rotational motion, Off-set loads, ISO 5344. Test specification parameters and their interpretation. “Bring your specifications”, Frequency, displacement, velocity & acceleration, dB, Sweep rates (log, linear), Resonance search and resonance dwell, Servo systems, Compression rates, Measurement modes (peak, rms, tracking filters). Test tolerance, Notching, Control methods: averaging, extremal, Control problems, Spectrum analysis, FFT, anti-aliasing, windows, PSD (ASD) g²/Hz, m²/s³, Slopes dB/octave dB/decade, Total acceleration rms, grms, m/s²rms, Crest factor, Sigma, Resolution, Bandwidth, Channels of analysis, DOF, Out of band energy, Narrow band random, Velocity rms, Displacement rms, Road load data, MIL and IEC specifications. Shock/Bump/Transient, Pulse shapes, Pre/Post pulse, Compensation pulse, Optimisation. Accelerometers: Types, Positioning, Fixing, Calibration, Why log sweep?, What is crest factor? and more ……..

WHO SHOULD ATTEND?

  • People who are totally new to vibration testing.
  • People who are running vibration test systems and wish to improve their knowledge.
  • People who write vibration test specifications and need to understand the realities of vibration testing.
  • People who design products which have to survive vibration.
  • People about to purchase a vibration test system.
    • If you fit into one of these categories you will find the course both enlightening and extremely worthwhile.

    MAIN COURSE AIMS

    To enable the delegates to :

  • Interpret a sine / random / transient test specification to determine the system requirements and limitations.
  • Understand the terminology used in vibration testing.
  • Discuss the suitability and practicality of a given test.
  • Set-up and run a sine / random / transient test (shock / bump).
    • ON SITE COURSES

    The Introduction to Vibration Course can be run on your premises and would be tailored to your specific needs and requirements.
