Metal yield type energy dissipation testing machine

The utility model belongs to the technical field of instruments and meters, and relates to a metal yield type energy dissipation testing machine. Comprising a main machine frame, an inclined strut, a sliding rail, a sliding block, a driving motor, a stopping block, a wedge key, a bottom beam, a stand column, an adjusting longitudinal beam, an adjusting oil cylinder, a cross beam, an upper pressing beam, a lower pressing beam, an adjusting stand column, a horizontal displacement meter, a magnetic meter seat, a meter frame, a servo loading system, a front spherical hinge, a servo actuator, a force sensor, a rear spherical hinge and a test tool. Pin hinge devices are fixedly mounted at the lower ends of the cross beams. Through the arrangement of the parallelogram mechanism, the problem that the accuracy of experimental data is influenced by deviation of integral experimental data during an experiment due to low strength of a loading structure is solved, and through the arrangement of the pin hinge device, the p
