keywords = {<span>A two-stage energy absorption device combing expansion tubes and aluminium foam was introduced. The design basis included energy absorption characteristics of the two parts and required energy absorption value. The design method of the device was verified using quasi-static compression tests and drop weight impact tests. The result shows that the two- stage device achieved desired layered gradient stress platform. The finite element model of the device was established. Dynamic response and energy change characteristics under different impact conditions were analyzed using numerical simulation. The energy absorption ratio of aluminum foam and expansion tubes can reach 80%. Remaining components can be reused after replacing main energy-consumption parts. An optimization method is proposed based on its adverse failure mode. The utilization rate of energy dissipation materials and the overall stability of the device are increased.&nbsp;<br />
