Principles of Vibration Measurement and Analysis

This user seminar introduces vibration theory and the measurement of vibration.  The seminar emphasizes proper use of vibration instrumentation, and covers the measurement chain from transducer to vibration meters and frequency analyzers.  Afternoon workshops allow attendees to gain "hands-on" experience with vibration measurements.  Recommended for engineers involved with product design, quality assurance, or R&D.

Principles of Acoustics and the Measurement of Sound

A seminar for people concerned with the understanding, measurement and description of sound and noise.  It includes an explanation of the fundamentals of acoustical terminology, means of describing noise for industrial products and community applications, noise generation processes,
and an explanation and demonstration of equipment and techniques for noise
measurement.

Sound Intensity

Learn the theory and use of sound intensity measurements. Sound Intensity techniques obtain results without the special test facilities of traditional methods ... often in less time ... and will be compared to conventional  measurement techniques.

Applications, methods of measurement, instrument techniques, and practical 
considerations will be covered. Both filter and FFT-based intensity systems will be available. 1/3 of the course time is devoted to demonstration and hands-on.

Understanding Modal Analysis

The dynamic properties of structures often contribute to excessive vibration which produces high noise levels, fatigue failure, premature wear, operator discomfort, and unsafe operating conditions. Modal analysis is the process of determining the dynamic characteristics of structures and is the most effective method for investigating the above problems. Modal analysis is used to determine a mathematical model of a structure based on its natural frequencies, mode shapes and damping factors. The model can then be used to verify finite element analyses, and to simulate and predict fatigue failure problems.

This one-day seminar gives a broad introduction to modal analysis from basic definitions to advanced applications of a modal model. Demonstrations are used throughout to emphasize physical interpretation of structural dynamic concepts. Attendees will have the opportunity to view several examples of structural problems and the classic film showing the destruction of the Tacoma Narrows Bridge.

Topics Include:

  • Introduction to Modal Analysis
Definitions - Modal parameters - Modal model
  • Frequency Response Functions
Dynamic characteristics via FRF's - Driving point response. Frequency response function matrix
  • Modal Test Procedure
Instrumentation - Excitation techniques
Calibrations
  • Computer Aided Modal Analysis
Computerized procedures - Curve fitting
Animation of mode shapes
  • Application of the Modal Model Engineering analyses
Problem diagnosis
Problem solution
