Tuesday Vibes - May 2nd

Experimental Modal Analysis: A Practical Overview???

by Peter Avitabile, Ph.D.

Wednesday July 26th & Thursday July 27th

Modal analysis is an essential technology behind solving noise and vibration problems. This seminar focuses on the measurements needed to make a successful test as well as the reduction of that data to obtain the dynamic characteristics of a structure or system – that is the frequency, damping and mode shapes. Discussion on some of the common pitfalls and misconceptions are presented in this seminar. Impact measurements will be made to illustrate a typical modal test with a roving hammer. In addition, measurements with also be taken with SIMO and MIMO shaker data acquisition. Data acquired will be reduced to show the entire process for development of the modal model.?

Seminar will be led by: Dr. Pete Avitabile, Professor Emeritus University of Massachusetts Lowell

Basics of Modal Testing & Analysis

Pre-Conference Workshop, Tuesday July 25th

Speaker:?John?Hiatt,?Application Engineer / Business Development,?DEWESoft

Want to understand how structures respond to forces?? You are invited to attend a 1/2-day tutorial/walk through on the modal analysis process.?This presentation will not require attendees to have previous knowledge of the topic.??Both presentations and demonstrations, will be used to explain structural dynamics concepts. Best Practices and lessons learned will be provided.??

Who Should Attend:?Engineers, Technicians and Analyst who want to learn more about the modal analysis process
