ABSTRACT:
A mass damper for a dynamically excited part including a housing connected in a vibration-free manner with the part and a spring-mass system that can vibrate in the direction of the excitation of the part. The spring-mass system comprises a leaf-spring arrangement tensioned firmly to the housing on one side and provided on the other side at the free spring end with an inertial mass. Resonance adjustment is performed in a structurally simple and problem-free manner, solely by control interventions on the housing side and without mass shifts in the spring-mass system. The inertial mass is permanently connected with the free end of the leaf spring, and, in the vicinity of the tensioning point or at a distance from the point, a variably adjustable leaf-spring support for adjusting the resonant frequency is provided with variable tensioning geometry or internal stiffness.
