FIELD: test engineering.
SUBSTANCE: device contains two electric-magnetic force actuators connected to an energy storage unit, two coaxially installed drive rods for transition of forces to a sample, and devices for observing of deformation mode of the sample. The drive rods are performed in the form of waveguides-concentrators and joint to the external side of the power actuators located between waveguides-concentrators. The waveguides-concentrators have thread holes for securing of the sample.
EFFECT: increasing of transformation efficiency of electrical power into mechanical force and increasing of information value and accuracy of test results of constructional materials for dynamic tension, as well as simplification of a design.
