Measurement Techniques: Excitation and Analysis

This lecture covers the measurement of frequency response functions, visualization of structural modes, and the effect of mass addition on structures. It explains the proper mounting of wings, selection of data-acquisition parameters, and the use of different hammer heads for exciting the wing. The lecture also discusses the analysis of time domain and frequency responses, measurement of resonance frequencies and mode shapes using FRF analysis, and the impact of adding magnets to increase the weight of the wing. Additionally, it explores different types of hammer heads, time and frequency domain responses, and various signal processing techniques. Practical work documentation and report submission details are also provided.
