摘要Purpose - The purpose of this paper is to improve the crashworthiness of aircraft by using the strut system as an energy absorption device without redesigning other components. Design/methodology/approach - The novel strut system consists of metal stepped thin-walled tubes and articulated connecting hinges. The strut is suffering axial load during impact process for rotating of hinges, and the metal stepped tube has an inversion failure behaviour. Findings - The metal stepped tube has lower initial impact load and more stable failure behaviour. The geometrical factors have a great influence on the impact load and energy absorption efficiency. The best length ratio between upper and lower sections is about 2: 1 and 1: 1 for the metal stepped circular and square tubes, respectively. Practical implications - The metal stepped tube with inversion mechanism is suitable for aircraft strut system to improve crashworthiness performance. Originality/value - A new strut system is provided using metal inversion failure stepped tubes and articulated connecting hinges to improve crash worthiness of aircraft.
