The control of vibrations in beams or other one-dimensional structures is of considerable interest in practical engineering. With the majority of industrial applications it is this type of structure, for example, pipework vibrating at low frequencies and other mechanical linkages which forms one of the main vibration paths which bypass isolator systems. In addition to this, it is well known that the introduction of discontinuities into these types of structure significantly affects the vibration transmission properties of the complete installation. One such discontinuity that may be employed as a vibration control device is the vibration neutralizer (often referred to as a 'dynamic Vibration Absorber'). Previous research in this area has employed both theoretical and numerical parameter studies on the effects of utilising these types of device for practical vibration control purposes. In this work complimentary experimental studies are presented with view to validating those previously presented theoretical results. In the experimental work considered here flexural vibrations only are considered and it is shown that by using the concept of vibrational power transmission it is possible to design and test practical flexural vibration control devices on an experimental pipeline structure.
