Popis: An instrument for determining the coordinates of impacts in thin-walled structures (up to 3 mm in thickness) on the basis of a rule of ferroelectric dynamic strain gauges is developed. Dynamic strain microgauges based on films of Pb(Zr0.53Ti0.47)O3 2.0 μm in thickness with contact area 0.8 mm2 are used. Tests of the instrument according to an algorithm that detects the phase differences of deformation waves demonstrate that the relative error of the impact site determination does not exceed 14%.
