SUSPENSION ARRANGEMENT FOR A BODY VIBRATING AT RESONANCE FREQUENCY

摘要

A body, which oscillates or vibrates at resonance, is suspended from a support structure so that it has spatially linear motion along an axis for a relatively short distance. The body has two connected portions spaced from each other along the axis of motion of the body with each portion connected by leaf springs to a separate intermediate frame. The two intermediate frames are preferably disposed on opposite sides of the axis of motion of the body and connected by additional leaf springs to a main frame, which is suspended by leaf springs from a normally stationary support. If desired, the two intermediate frames may be driven out of phase with each other with one in phase with the body so that the body has a predetermined path different than spatially linear motion without materially affecting the amplitude of motion of the body along its axis of motion.
