Abstract
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 the punch housing when it moves in the soil. Methods of recording dynamic characteristics of working cycles of the hydraulic device are worked out. Tests were carried out with changes in the force acting on the housing from the clamping device. Oscillograms of the characteristics of working cycles (displacements of the housing and striker, pressures in the working chambers and the accumulator) are given.
