The article is dedicated to development of the study methods of the thin-walled detail fabrication by electrohydraulic stampings job, as well as analysis of its regularities and particularities. It is considered technological system with one submersible camera. Are discussed the dynamic mechanical processes in pulsed technological heterogeneous system, including the electric discharge channel transforming into vapor-gas cavity, viscous- elastic technological liquid, elastic-plastic shell, hard technologic attachments. For analysis of the processes together used methods of the experimental study and mathematical simulation by numerical decision of the contact dynamic problems continuum mechanics. Are described particularities of the kinetics of processes. Are compared results of two methods. On the basis of modeling data system elements interaction, is given explanation of experimental results. Are made conclusions about adequacy of the mathematical model and accuracy of the simulation method. The results may be useful at development and optimization new, as well as modification existing technological equipment and parameter for the reason increasing of efficiency of the technological process and workmanship of the details.
