Effect of electrical circuits on duration of an acoustic pulse radiated by a piezoplate.
By means of numerical computation, pulse mode of a piezoelectric radiator in the form of a plate, loaded with a liquid and connected to R-L circuits in various combinations, is investigated. The computations were carried out having taken into account the internal resistance of the electric generator. Numerical results, based on the theory, are provided for examples of parallel and series circuits connected to a piezoelectric plate. The optimal values of parameters are determined, providing minimal duration of radiated acoustic pulses.
