Known designs and dynamic circuits of piezoelectric transducers for recording pulse-type vibration have been briefly reviewed. Their merits and shortcomings were discussed. Designs of piezoelectric accelerometers with various mechanical strain of a piezoelement (compression, tensile, shear, flexural strain or complexly stressed state of a piezoelement) and those of resonance and semiresonance sensors were also considered. Capabilities of the following dynamic circuits of transducers were analyzed: vibrating systems with localized elements having one or two degrees of freedom, vibrating systems with distributed parameters (with a sufficient number of degrees of freedom). To calculate the systems with distributed parameters, differential (wave) equations are used in partial derivatives having variables which characterize the dependence of studied values not only on time, but also on spacial position of all the system points. Analysis of design and dynamic circuits of piezoelectric transducers allowed to choose the circuits which are most optimal for the design of specific knock sensors and to provide some recommendations for further designing of different piezoelectric transducers for pulse -type vibration recording.
