An apparatus for generating vibrations in a component comprising a clamp assembly for clamping the component and a vibration generator for generating vibrations in the clamped component, the clamp assembly (1) including: a base member (3a), a pair of fixedly-spaced clamp members (3b,3c) and a wedge (9) for laterally wedging part of the component between the clamp members (3b,3c) thereby to clamp the component. The base member (3a), or a fixed clamp member (3b,3c), is inclined and the wedge (9) having an inclined wedging surface (9b) arranged to engage the inclined base member (3a) or inclined fixed clamp member (3b,3c). The apparatus may form part of a test rig for vibration testing components such as turbo machine blades.
