An arrangement for controlling the vibratory behavior of an integral structural component includes at least one element of memory metal material two portions of which that are spaced by a predetermined distance from one another in a first state of the memory metal material are connected while the memory metal material is in its first state to respective locations of the integral structural component that are spaced substantially by the predetermined distance from each other along a region of the integral structural component which undergoes considerable cyclical dimensional changes while the integral structural component vibrates. This element is then heated, such as by causing electric current to flow therethrough, either from time to time as required, or at a certain frequency, to above a temperature of transition of the memory metal material to its second state in which the spacing between the two portions of the element differs from the predetermined distance with attendant change in the vibratory behavior of the integral structural element such as to suppress or generate vibrations of the integral structural component especially at its natural resonance frequency.
