Crashworthiness of Civil Aircraft Subject to Soft Soil and Concrete Impact Surface
The impact response of civil aircraft subject to different soft soil and concrete ground is investigated. Typical finite element model of fuselage section is built based on sound simplification. Several different soft soil and concrete impact surfaces are adopted here. The drop test of civil aircraft is conducted subject to 7m/s impact velocity. The impact response of ground and civil aircraft are revealed. Result shows that ground material has great influence on the crashworthiness of civil aircraft. Soft soil ground could dissipate a part of impact kinetic energy, and failure element of concrete ground would be deleted. Ground with larger stiffness would absorb less internal energy and undergo smaller deformation. The relevant civil aircraft would also have larger plastic deformation, and greater initial peak acceleration would be suffered by occupant.
