摘要

This paper deals with the problem of the dynamic behavior of a plate on elastic foundation under the action of forces produced by a landing airplane. A partially plastic impact is postulated for the contact between the airplane and the plate. The Winkler model is used to simulate the ground's elastic behavior, by which the foundation reaction is proportional to the plate deflection, along with dampers for energy dissipation. Two models are used for the airplane, i.e. a simplified mass-load model and a mass-dashpot-spring model, and their influences on the dynamic response of the plate are evaluated. Moreover, various parameters concerning the salient features of the airplane and its landing on the plate are studied with conclusions drawn. The efficiency of the methodology proposed herein was demonstrated in the numerical study.
