An experimental investigation and a numerical simulation of detonation excitation of TATB explosives were undertaken. The experimental investigation was carried out for a detonation excitation at an interaction of shocks with different intensity as well as for the effects of desensitizing (explosive sensitivity decrease) and sensitizing (explosive sensitivity increase). A numerical simulation of experiments was performed on LEGAK complex using kinetics of explosion decomposition, proposed by Morozov group and implemented in Lagrangian setting in DMK, MIMOZA and D-methods. Kinetics model was generalized to non Lagrangian calculational grid. Calculational results and their comparison with experimental data are presented. The experimental and calculational data agree with each other. The whole set of experiments has been described with fixed kinetic and calculation parameters.
