A METHOD FOR SOLVING THE INVERSE LOCAL DYNAMIC MODIFICATION PROBLEMS OF MECHANICAL STRUCTURES

Yu Dejie (Hunan University)  
In this paper, a method for modifying the local stiffness and mass parameters of a mechanical structure so that the structure will freely vibrate at a prescribed frequency is proposed. The gen eral expression of the modification results of mass and stiffness parameters is also derived. This method uses only the dynamic flexbility data on the degrees of freedoms connected to the modify ing parameters, therefore, it is simple in computation and experimentation. A numerical example is given to show the effectiveness of the proposed method.
