FIELD: machine building.
SUBSTANCE: test bench consists of base, of stationary sample support mounted on base, of movable sample support, of loading mechanism connected to movable support and including falling load, of platform positioned under movable support, of flexible element with non-linear characteristic of stiffness located under platform, and of unilateral grippers mounted on movable support and interacting with load at its motion upward under recovery force of flexible element. The flexible element corresponds to a set of arc-shaped bent plates with different radius of curvature successively arranged with decrease of radius and contacting one another, or arranged with pads of specified thickness between them.
EFFECT: analysis of power exchange at stepwise changing diagrams of energy accumulation and transfer at wide change of parametres.
