Abstract
A resonance testing apparatus has a plurality of arms for supporting a workpiece. At least one of said arms incorporates an articulation assembly having: a strut, a joint element which is movable in response to movement of the strut, and a clamp arrangement for clamping the joint element. The assembly has a first condition in which the joint element is movable and a second condition in which the clamp arrangement acts on the joint element to damp or restrict movement of the strut. The assembly includes a seating for the joint element, and a biasing arrangement for the seating. The assembly has a first condition in which the joint element is arranged on the seating and is movable on the seating and a second condition in which the biasing arrangement acts on the seating to damp or restrict movement of the joint element on the seating.
