DEVICE FOR TESTING IN EXCITATION OF MULTI-CYCLE LOAD DAMPED VIBRATIONS ON TESTED SPECIMEN Russian patent published in 2010 - IPC G01N3/34 

FIELD: instrument making.

SUBSTANCE: invention relates to test equipment, particularly, to structural strength tests. Proposed device comprises base supporting specimen passive element, active gripper, vibration exciter coupled with said active gripper and flexible element with weight connected thereto. Note that proposed device incorporates extra vibration exciters with flexible elements and weights connected thereto, flexible tie with its one end connected to active gripper, and tensioning mechanism connected with the second end of said tie. Note here that vibration exciters are arranged along the tie, flexible elements are connected thereto, tensioning mechanism represents a press, flexible elements feature unequal rigidity and weights feature unequal weigh.

EFFECT: increased volume of data due to testing in excitation of multi-cycle load damped vibrations on tested specimen.
