TEST BENCH OF ENERGY INTERCHANGE AT DESTRUCTION Russian patent published in 2014 - IPC G01N3/08 

FIELD: test equipment.

SUBSTANCE: test bench of energy interchange at destruction includes a housing, specimen grips installed on it, a loading mechanism including two flexible tie-rods connected on one of their ends to the grips, a rotary actuator, a load fluctuation exciter installed on the rotary actuator shaft and located between tie-rods, and a tension mechanism connected to the other end of flexible tie-rods. The bench is equipped with a platform and a platform movement actuator. The rotary actuator is arranged on the platform; the movement actuator is made so that it provides movement of the rotary actuator along the shaft axis. The load fluctuation exciter is made in the form of a triangle, the base of which is fixed on the rotary actuator shaft, and height is directed along the shaft axis. Flexible tie-rods have a displacement limit stop in the platform movement direction.

EFFECT: performance of tests under new conditions: at transitions from cyclic loadings with smooth control of cycle amplitude to constant long-acting or step-by-step changed loads, as well as to subsequently changing loads at arbitrary alternation of loading types during tests without any specimen unloading.
