Patent ID: 8650956

Claim:
A vibration test arrangement for a component, the arrangement comprising: means for holding a first end of the component while a second end of the component is unrestrained and free to vibrate; means for vibrating the component; and an isolation device arranged to engage the component upon a node line of a mode of vibration to isolate a mode of vibration of interest, the isolation device having a first isolation member and a second isolation member, the first isolation member and the second isolation member mounted with a clamp association to provide an isolation abutment pressure between the first isolation member and the second isolation member, the clamp association comprising a displacement mechanism to provide relative displacement between the first isolation member and the second isolation member, and the displacement mechanism being associated with a controller and the controller being associated with a sensor to determine the isolation abutment pressure, the sensor providing signals to the displacement mechanism to alter the isolation abutment pressure.
