摘要

The problem of identification of concentrated mass and spring stiffness on non-terminal points of the rod from the known first two natural frequencies is solved theoretically. The sufficient conditions for the existence of a unique solution of the problem are found. On the basis of the model, discussed in this paper, an operation algorithm of the device for the non-destructive testing is suggested.
