TESTING MACHINE Russian patent published in 2005 - IPC

FIELD: testing engineering.

SUBSTANCE: testing machine comprises load-bearing frame composed of the base with power hydraulic cylinder and cross-member interconnected through columns, active and passive grips for setting the articles to be tested, which are connected with the rod of the power hydraulic cylinder and cross-member, respectively, hydraulic drive system, electrical dynamometer, pickup of displacement of the active grip, and electrical system for control and measuring of load and deformation. The rod of the power hydraulic cylinder is provided with the axial opening, which receives additional hydraulic cylinder whose rod is connected with the active grip. The cross-member receives an additional dynamometer connected with the passive grip through a tie. The active and passive grips are provided with couplings, which disconnect them from the rod of the main power cylinder and cross-member, respectively. The columns are connected to the cross-member through electrical dynamometers. The outputs of the dynamometers are connected with an adder.

EFFECT: enhanced reliability of testing.
