Experimental Modal Measurement and Analysis Seminar
199.00

Modal analysis is an essential technology behind solving today’s noise and vibration problems. Dr. Peter Avitabile, Professor Emeritus at University of Massachusetts Lowell, will discuss taking measurements – along with the pitfalls, difficulties, and common misconceptions related to modal testing. This seminar will focus on the practical aspects of impact and shaker measurements, the most common methods used to acquire data for experimental modal analysis.

Who Should Attend
Engineers and technicians who currently practice or need to learn how to make proper measurements for experimental modal tests.

The cost of the training is $199.  This fee covers course, training materials, and meals.
