A METHOD FOR CALCULATING PLATE AIRFIELD COVERINGS UNDER THE ACTION OF AN INERTIAL LOAD DURING ITS BRAKING USING AN AERIAL FINISHER

A method for calculating plates under the action of force and inertial loads during their movement with variable acceleration is proposed. The problem of the interaction of an aircraft load, at the moment of its movement in braking mode when using an aerial finisher, with a coating in the form of a rectangular plate of elongated dimensions on an elastic base is considered. Nonlinear contacts of the chassis wheels are taken into account when using piecewise linear characteristics of contact stiffness. The vertical dynamics of the spatial model of the aircraft during the run is modeled by a system of rigid bodies with elastic-viscous bonds. To construct the methodology, the step method proposed earlier by the author of the article is used to solve problems of unsteady dynamics of structures and the method of calculating structures for the action of mobile force and inertial loads (the method of nodal accelerations).
