A Dynamic Analysis of an Integrated Aircraft-Floating Structure-Water Interaction System Excited by the Impact of an Aircraft Landing

摘要

The dynamic response of an integrated aircraft - floating structure - water interaction system excited by the impact of an aircraft landing is investigated. The aircraft and the floating structure are considered as two elastic substructures and the water is treated as a fluid subdomain. The landing gears of the aircraft are modeled by three supporting systems, each consisting of a spring and a damper. A mixed finite element - boundary element approach is developed to model this complex interaction system. The solution strategies of the numerical equations are proposed. A 2-dimensional numerical example is presented to illustrate and to demonstrate the mathematical model and the numerical method.
