The 2nd Annual Prosig Prize for Engineering at Portsmouth University has been awarded to Ashley Stehr for his project “Developing an engineering mechanism to reduce the effects of rapid rotational motion caused by the shocks inherent with high speed craft”. Ashley is in his third year studying for an MSc in Mechanical Engineering. His project was supervised by Dr Ya Huang. Ashley’s project poster is shown below (click for a larger view).
The aim of the project was to look at ways of mitigating the effects of rolling motion caused by high speed shocks in fast boats, specifically, a Tamar class lifeboat. Human vibration in ground vehicles is well understood and fairly easy to measure and analyse. In water craft the problem is made more difficult by the rolling motion and its effect on the spine. The RNLI provided some of the design specifications for the Tarmar class, which was used as a target user environment. Frazer-Nash Consultancy (Bristol) provided some technical advice at the initial stage of the project.
The study is ongoing and is intended to form part of a Year 4 group project next year.
Prosig congratulate Ashley on his work and wish him every success in the remainder of his course and future career.
