CIRCUIT RLC EN REGIME TRANSITOIRE PDF

The present invention relates to a method and device elimination of transient regimes of piezoelectric transducers. The main application of the invention is the use of such transducers in the transmission in a sound wave liquid, essentially, on the one hand during the tests and measurements that one wants with these immersed transducers, in tanks which cause then reflected waves or echoes disturbing the measurements, and other hand, when we want to instantly transmit orders from control through hydraulic circuits. In this type of tests in particular, we want to calibrate the transducers electroacoustics to assess their performance in the environment marine, by measuring for their industrial validation, the parameters characteristics one of which is the measurement of emission sensitivity, which is the sound pressure emitted in the far field in the axis at a distance of one meter: for this, the transducer is immersed in a tank and is excited by a sine wave train, which is noted by a hydrophone, the appearance of the sound field emitted by this projector; however, in a tank whose dimensions are necessarily limited, many echoes are returned by the walls and disturb the measurement such sensitivities: an assembly diagram is shown in the figure 1 attached. So, to have a good measure of the response of the transducer, this must be done during the steady state and before the arrival of said echoes.

The result is a second-order differential equation for any voltage or current of interest. What we learned in Chap.
