ABSTRACT:
A flexure assembly that is particularly useful in vibration testing equipment provides a noiseless, frictionless support that allows motion in a desired direction while restricting motion in other directions. The flexure assembly includes a flexure arm that is made from a material that is at least partially flexible in one direction while being stiff in at least two other directions, which are generally perpendicular to the one direction. A first end of the flexure arm is adapted to be rigidly secured to a moving portion in a vibration testing device, for example. A second end of the flexure arm is rigidly secured to a mounting block. The mounting block is also rigidly secured to two flexure leaves, which are also made from a material that is at least partially flexible in one direction while being stiff in at least two other, generally perpendicular, directions. A second end of the flexure leaves are rigidly secured to a second mounting block, which is adapted to be secured to a base within a vibration testing device, for example. The flexure arm and flexure leaves preferably are made from stainless steel and are generally planar and generally rectangular.
