Abstract
The mathematical model of the one-way hydraulic positive-displacement system with two piston stop tools includes the design variables of the system and its interaction with rock mass, namely, dry friction in the impact facility body–piston couple, pressure losses in the hydraulic system branches and piston velocity recovery factor. The dynamic similarity criteria, which are dimensionless analogs of the listed characteristics, are determined. The numerical calculation is performed, the influence of the similarity criteria on the dynamics and integral characteristics of the test system is analyzed, and the main behavioral patterns are revealed. It is found that these criteria influence the shape of the domains of the single impact travel and back run, two-impact and multi-impact limit cycles. It is possible to reduce the difference between the system characteristics in the impact travel and back run by means of changing the piston coordinates such that the valve stations are changed.
