This paper deals with simple supported beam-actuators-concentrated masses mechanical system; It appears in active vibration reduction problem. To solve the problem with the Fourier method, the system is discretized into uniform: elements. In the paper the orthogonality condition of the modes of the discretized system is derived. Furthermore, the solution of the forced vibration problem of the above system, appearing inherently in the active vibration reduction problem, is outlined.
