Universal testing machine for research materials under high hydrostatic pressure

摘要

Universal testing machine for research materials under high hydrostatic pressure. The invention relates to the field of test devices and can be used for mechanical testing of tubular and cylindrical solid samples in a complex state of stress under the simultaneous action of high hydrostatic pressure.; Universal testing machine comprises a base - testing machine torsion KM-50 on which is mounted a power circuit consisting of two force plates interconnected by columns, high-pressure cylinder fixed with two supports, torsion mechanism, the motor, the upper plunger high pressure , the lower plunger high pressure, as a mechanism for axial loading of the hydraulic cylinder is used, part of the low pressure hydraulic actuator, which is controlled at pom oschi proportional control valve. The loading of the sample axial force and torque is performed by the control computer with industrial automation. To determine the strain and stress are used strain gauges are used as well as feedback.; Using the proposed utility model allows to perform construction of arbitrary trajectories in space deformations or stresses at hydrostatic pressures up to 500 MPa, which will allow for a more complete and correct research processes of plastic deformation and fracture, predict and control the formation of product quality obtained metal forming processing, increase efficiency technological processes.
