Method for identifying transfer function of piezoelectric sensor of pulsates electro-acoustic cell in test bench, involves repeating initial and final distribution loads calculating steps when result of comparison is negative

摘要

The method involves calculating an initial distribution load from a value to which a parameter is initialized (115). A final distribution load is calculated (150) from a detected digitized signal and inverse of a transfer matrix. Parameter values of modeling functions of loads are compared (170) with each other. The initial and final distribution load calculating steps are repeated (180) by considering the parameter values of the modeling functions of the initial and final distribution loads to be equal when the result of the comparison is negative. Independent claims are also included for the following: (1) an information recording medium comprising a set of instructions for performing a method for identifying a transfer function of a piezoelectric sensor of a pulsates electro-acoustic (PEA) cell in a test bench (2) a device for identifying a transfer function of a piezoelectric sensor of a PEA cell in a test bench.
