Abstract
A flexural spring support for a vibratory apparatus comprises a substantially stationary first member, a second member disposed opposite and spaced from said first member and intended to undergo translating motion in a plane, and a plurality of elongated flexural springs coupling said members to one another. Each spring is provided at its ends with a respective flange, the underside of which is in forced engagement with the surface of the associated member. Adjustable fastening means cause the engagement pressure to be of such magnitude as to prevent relative motion between the flange and member surface when said first member undergoes motion, thereby substantially eliminating fretting corrosion previously manifest at the springs. In addition, each spring is configured to form a clamped clamped constant strain tapered beam.
