    Notes: Abstract The method of the moment excitation in the studies of the structureborne sound using a moment actuator is introduced. Some design considerations for the moment actuator are presented. A standard mechanical system is established to calibrate the performance of the moment actuator. The frequency and mechanical power performances of the actuator are discussed.

    Notes: Abstract In this paper, the measuring methods of the rotational components, i. e. the free angular velocity and the moment mobility are presented. The performance of a moment actuator composed of two magnetostrictive rods (Tb0.3 Dy0.7 Fe1.95) is discussed. Both theory and experiment show that the performance of the moment actuator does not influence the measurement results of the moment mobilities basically but affects the efficiency for exciting rotation. The efficiency for exciting rotation has also been calculated.
