A physical model and a stand for the research of a single-acting hydroimpact device
Autor: L. V. Gorodilov, V. G. Kudryavcev, A. I. Pershin
Publikováno v: Interexpo GEO-Siberia. 2:265-269
The paper presents a physical model of a single-acting hydroimpact device. Its design can be used to create a hydraulic punch for drilling wells in soft soils. A stand with a clamping device has been developed to simulate the friction force acting on

Evaluation of ways to improve the reliability of the spool distributor of a hydroham-mer with a delay in the movement of the striker
Autor: L. V. Gorodilov, V. G. Kudryavcev
Publikováno v: Interexpo GEO-Siberia. 2:115-122
A spool distributor is considered, which makes it possible to delay the movement of the striker of the hydraulic impact device and thus maintain the impact energy at a given level. Schemes for improving the design of the distributor are proposed, aim

BASIC PROPERTIES OF ONE-WAY ACTION HYDRAULIC PERCUSSION SYSTEM WITH TWO PISTON ARRESTERS
Autor: L. V. Gorodilov
Publikováno v: Journal of Mining Science. 56:972-981
The author presents the mathematical model of an autooscillating one-way action and positive-displacement system with two piston arresters. The dynamic criteria of similarity are determined, including: stiffness ratio of springs of the accumulator an
