Cost Effective Impact Attenuator for a Formula Student Car

摘要

Vehicle safety is one of the major fields of research in automotive industry. While the use of SRS, Dual Stage Airbags, etc. have become prevalent nowadays, designing of a Crash-worthy structure such as impact attenuator still stays one of core and efficient system. There are many impact attenuators available in the market basically made from aluminum or impact foam material. The basic structure of this impact attenuator is the honeycomb structure, but a major problem is the cost of the manufacturing and compatibility with the rules that we have to follow for the competition. So, we decided to use the "BEVERAGE TINS" which are also made up of aluminum alloys. The final design was a result of the various arrangements of tins that we tested on an UTM. The report mainly concerns with the design and development of an impact attenuator for the Formula Student Car being economic, innovative and easy to manufacture.
