Definition

An experimental modal testing procedure performed on an aircraft, vehicle, or structural assembly while supported on ground fixtures that measures modal frequencies, damping ratios, and mode shapes by applying controlled excitation (shakers or impact) and recording responses at sensor locations; results are used to validate/update finite‑element models and to assess dynamic characteristics relevan
