As always, here at Swansea Metropolitan University, we hold reliability in high regard. This has stood to us in the last number of years, regularly finishing amongst the top of the UK teams. Our contender for 2011 is no exception, and with testing commencing in March we have worked on some exciting dynamic developments including both tyre and differential programmes, showing a substantial increase in performance. The use of strain-gauges during testing has allowed us to validate FEA carried out on all components giving us a better understanding of how long parts will last, helping to avoid costly failures and also has been a help in allowing us to reduce weight further. Our small team of diversely skilled undergraduates has been focusing on improving the car in all areas. Developments include a thorough weight reduction programme, including the integration of composite technology where possible. A completely re-worked chassis design, retaining the T45 spaceframe layout, has been designed around our CBR600rr engine. Back to back dyno testing with different fuels, plenums and cylinder heads has allowed us to optimise the performance. The final product is an overall more elegant, driver focused, and lightweight machine.
