Summary:By using Double external cavity Fabry-Perot interferometer..DEFPI..to measure the shock wave overpressure generated during the explosion, Combined with Ansys/LS-dyna nonlinear finite element analysis, Simulation analysis of pressure cloud map of blast wave propagation in air and the pressure schedule with different explosion. Design sensor layout and accurately measure shock wave overpressure signals at various locations in the explosion field. The solution overcomes the instant, multi-point, electromagnetic interference, long distance transmission of the explosion process, can improve the Confidence level of weapon system damage effect assessment.
