A Dynamic Analysis of an Integrated Aircraft-Floating Structure-Water Interaction System Excited by the Impact of an Aircraft Landing
نویسنده
چکیده
The dynamic response of an integrated aircraft-floating structure-water interaction system excited by the impact of a landing aircraft is investigated. The aircraft and the floating structure are considered 2 elastic substructures, and the water is treated as a fluid subdomain. The landing gears of the aircraft are modeled by 3 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 demonstrate the mathematical model and the numerical method.
