Vibration Course

Shock and Vibration Training course by Tom Irvine

When: 10th of September 2015

Where: Faculty of Mechanical Engineering, University of Ljubljana (5min walk from the conference site)

Duration: one day (4h in the morning and 4h in the afternoon)

Morning Session: Shock Response Spectra & Time History Synthesis

This session covers classical, seismic and pyrotechnic shock. Students will receive basic instruction in calculating shock response spectra for time histories and for synthesizing time histories to meet shock response spectra specifications. The synthesis is performed using wavelets and damped sine functions. Students will receive software programs in both C/C++, Matlab & Python for making these calculations, as well as accompanying pdf files with formulas.

Afternoon Session: Fatigue - Rainflow Cycle Counting for Random Vibration Fatigue Analysis

Students will learn the basics of the rainflow cycle counting method in both the time and frequency domains. The rainflow results can be fed into Miner's cumulative damage index (CDI). Examples will be given for metallic structures and an electronics circuit board, where each system is subjected to a random vibration base input. The fatigue damage spectrum will be also introduced, including its usefulness for characterizing nonstationary vibration. Students will receive software written in C/C++ & Matlab for making the rainflow calculations.
