In clause the stand for research of shock systems is presented. The technique of experimental researches of the stand is stated and results of researches are presented. The necessary equipment for researches is presented. Efficiency of application in designs pnevmo- and hydropunchers of the dual shock system is proved. The further researches of shock system «piston-beat-bar» are stated.
The results of studies of impact processes, including the system piston - striker - rod, are considered. The energy of the shock pulse family at the impact of the piston with the striker is 10-20 % higher than this indicator at the impact with the solid piston. Based on the results of bench studies, the design of a perforator with a dual percussion system was designed and tested in the conditions of the Kirov mine of ОАО Apatit.
