“Experimental Vibration” An Insight to Practical Vibrations Introduction: Most of the Automotive, Aerospace and Defense establishments are relaying on experimental vibration studies to improve their design and reliability of products. There is need for many test engineers at this moment. With this well planned hands on training course using industry standard test products, attendees will be well prepared to face challenging real world. Most of the US and European Universities are using same tools in their curriculum. Course Details: • Basics of Digital Signal Processing - Fourier analysis, Sampling theory, Frequency domain windowing, FFT • Basics of Measurements - Harmonic motion, Linear system relationships, Mathematical relationships, Frequency Response Function & coherence, Input, output & cross power, Time domain measurements, sensors for mechanical vibration measurements • Introduction to Modal Analysis - Modal definitions, visualization of vibration, Lumped, continuous & finite element models, Normal mode vs. transfer function method, Modal parameters • Excitation Techniques - Impact excitation method, Shaker excitation method, Acoustic excitation method, Excitation signal types • Single Degree of Freedom Systems - Characteristic equation, Transfer function Derivation, Transfer function on the S-plane, Transfer function in partial fraction form, Mass, stiffness and damping sensitivity • Modal Test Procedure and quality assessment - Test setup & fixturing, Computer model (display), Measurement procedures, Parameter estimation & animation • Modal Theory - SDOF modal testing model, MDOF modal testing model • Parameter Estimation Techniques- SDOF & MDOF curve fitting methods, Local & Global curve fitting methods • Other Related Topics - Operational deflection shapes, Documenting results with digital movies • Hands On Laboratory Exercises - Excitation techniques laboratory, Measurements laboratory, Curve fitting laboratory, Modal test of a Beam, Plate and Automobile model Duration: The Course is scheduled for 1.5 Months. The class will be conducted on weekends (Specifically on Saturdays). Each session will be for 3 hours. The entire course is designed such that the participants learn by doing practical’s only. Since the main audience targeted is VTU students, we do understand the internals and test schedules and the classes shall be adjusted accordingly. Limited students per batch.
