Abstract:
One of the most important problems facing the exploration, oil, gas and
mining industry is increasing productivity and quality of used machinery and technology.
This paper presents the results of the study of the stress-strain state of parts of a hydraulic
impact device. The investigated device has a source of low-frequency vibrations in the
form of a hydraulic vibrating module, including a base machine, an actuating element,
an electro-hydraulic control unit, and an electronic block for monitoring a technological
process. The electronic block for monitoring of technological process receives signals
from the sensor of flow and concentration of metal, installed at the outlet of the pumping
well, converts them with a recorder, a decoder, and a corrector, and transmits them to the
electro-hydraulic control unit, where electronic signals are transformed into hydraulic
ones and transmitted to the actuator. The purpose of the study is to investigate the
stress-strain state of components of a hydraulic impact device and its further use in the
exploration industry in good drilling. The ANSYS Explicit Dynamics module was used
to study the stress-strain state of hydraulic impact device components, which makes it
possible to analyze the physical picture of high-speed processes for objects subjected to
strictly non-linear, alternating dynamic loads. The strength verification was carried out
using the Mises maximum stress criterion. The criteria are based on the Mises-Hencky
theory, also known as the energy theory of deformation. As a result, the strength and
stiffness of the hydraulic impactor element are ensured. For the more loaded element,
