| Popis: | An important feature of the Formula SAE (Society of Automotive Engineers) race car design competition is that the car must withstand a certain level of frontal impact without intrusion into the driver foot-well area or damaging levels of deceleration to the driver himself. For the car to be competitive, any impact-absorbing structure must be lightweight and hence many teams use aluminium honeycomb inside the car's frontal nose cone. This paper considers an alternative approach based on an array of thin-walled circular tubes attached to the front bulkhead of the car. Experiments have been conducted at the University of Leeds to study the behaviour of empty and honeycomb-filled tubes subjected to quasi-static and dynamic loading. Aluminium (6063 T6 alloy) tubes filled with Nomex® HRH-10 honeycomb were employed in the current study. The experimental programme included five quasi-static tests and four dynamic tests. It was found that the honeycomb-filled tubes absorbed around 10% more energy than the empty tu... |
