  • Identification of hammering signal for construction of hammering test system

抄録

In this study, we present the inverse analysis for identification of the hammering signal and the cavity position in non-destructive hammering test. The performance function is defined by square sum of residual between the obtained and the computed sound pressure. Here, the problem is to find the input sound pressure so as to minimize the performance function. The formulation for this problem is carried out by the adjoint variable method, and the numerical simulation of the sound pressure propagation is carried out based on the wave equation and the finite element method. In addition, the identification of the cavity position is also carried out based on the adjoint variable and the finite element methods.
