Suspension arrangement for an oscillating body

A suspension arrangement including:

• an oscillating body movable along an axis at a selected resonant frequency;
• intermediate frame means spaced from said oscillating body in at least one direction substantially perpendicular to the axis of motion of said oscillating body;
• a main frame, said main frame having a mass greater than the total mass of said oscillating body and said intermediate frame means;
• first leaf spring means connecting said oscillating body to said intermediate frame means;
• second leaf spring means connecting said intermediate frame means to said main frame;
• each of said first leaf spring means and said second leaf spring means being disposed substantially perpendicular to the axis of motion of said oscillating body when said oscillating body is at rest;
• said first leaf spring means having a larger spring constant than said second leaf spring means;
• said first leaf spring means and said second leaf spring means having substantially the same degree of flex to cancel any displacements other than said oscillating body along its axis of motion so that said oscillating body has spatially linear motion along its axis of motion;
• means to compensate for lost energy during movement of said oscillating body along its axis of motion;
• support means to support said main frame, said main frame having vibrations relative to said support means;
• and means to substantially prevent transmission of vibrations from said main frame to said support means.
