In article are stated theoretical and practical studies of «fluctuation» process in striking system «piston – striker – shank». Influences frequency pulse is touched upon the problem on increase of the resource of the crash tool.
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.
In clause the variant of configuration of an agency to passed a complex for mines Metrostroja of Saint Petersburg is presented. Formulas and results of calculation of key parameters of an agency of a complex on the COMPUTER by Poderni R.J.'s technique for hydraulicimpact and modernized program KOR_N for hydraulic mills are resulted. Use of hydraulic mills of longitudinal rotation as an agency on working off of a face is proved. The cycle to passed works of a complex is stated.
A tunneling complex for St. Petersburg Metrostroy with the use of a manipulator with a water hammer as an actuator is considered. It is proposed to use a dual impact system in the design of the water hammer for effective rock destruction. Works on research of twin impact systems at interaction with rocks of different properties are carried out. An experimental improved stand for the study of impact systems in interaction with rocks has been created.
