A paper on material quality determination in gearing applications, using Barkhausen noise analysis, was judged the best of eight submissions to the British Gear Association at its annual congress.
A paper on material quality determination in gearing applications, using Barkhausen noise analysis, was judged the best of eight submissions to the British Gear Association at its annual congress.
The authors of the winning paper were Dr V Moorthy, a scientist at the Indira Gandhi Centre for Atomic Research, India, Dr Brian Shaw, of Newcastle University Design Unit, and Peter Hopkins, an equipment Project Manager with the Ministry of Defence.
Dr Moorthy, a former winner of young metallurgist and young engineer awards in recognition of research contributions, is currently a visiting research engineer at the Newcastle Design Unit.
Peter Hopkins, who collected the prize on behalf of the three authors during the BGA Annual Dinner from Mr Martin Redgard, Chief Engineer of sponsors Exxon Mobil, is responsible for providing technical advice and engineering support for submarine main propulsion gearboxes and lub oil systems.
The selection board comprised Mr.John Myers (Newcastle Design Unit), Chairman of the BGA Technical Committee, Dr Hellmuth Kohler (Bennett Associates) and Mr Ron Chester (Sumitomo (SHI) Cyclo Drive Europe Ltd).
The paper highlighted the great potential of Barkhausen noise analysis as a non-destructive method for use in the quality control of material properties.
The authors summarised the benefits and applications of the process in the field of hardened steel gear manufacture, amongst others, and discusses the potential for the technique in monitoring fatigue damage accumulated in service.
Examples of the practical application of the technique in marine gearing were also presented.
