FIELD: test equipment.
SUBSTANCE: device has circular chamber being aligned with rotor. There are balls with similar diameters inside circular chamber. Solidifying liquid is disposed in gaps among balls. Part of the balls are much lighter and elastic than others. Values of density and bulk elasticity module of material of lighter and more elastic balls differ from corresponding values of the rest balls by one order and four order. Soft vulcanized rubber and special alloy are used as material for balls.
EFFECT: improved reliability of test.
