Abstract：Amphibious aircraft is a special aircraft with hull-type bottom in their fuselage.The ability to take off and land in waves and wave resistance are the important indicators of measuring the performance of amphibious aircraft.Therefore，the analysis of the water-loading and water-sking response，which is used to improve the structure design of amphibious aircraft，is one of the key technologies to ensure the normal operation on water and avoid the loss of structural integrity.However，in the existing domestic publicly available research on the water dynamic response of water-landing and water-skiing，most of them are based on the rigid body assumption.With the continuous development of aviation technology，the flexibility of amphibious aircraft is gradually increasing，and the calculation accuracy gradually fails to meet engineering requirements.This paper proposes an analysis method for the water dynamic response of amphibious aircraft during water-landing and water-skiing.Based on the characteristics of large structural deformation and strong fluid nonlinearity，and on the basis of specification requirements，it considers both the elasticity of the aircraft body and the elastic dynamic effect of water loads，thus providing strong technical reference for the optimization of the structural design of amphibious aircraft and the improvement of specification clauses.
