Modeling of Interaction of the Mechatronic Unit Segments in the Adaptable Part of an Aircraft Wing

摘要

The work represents the results of modeling and studying the interaction of the mechatronic unit segments in an aircraft wing when an external impact is applied. The basis of the model of an adaptable wing main frame structure proposed is a mechatronic unit, which is designed to ensure the preset angle between the elements in the adaptable wing structure; a coordinated control of the model; and a possibility to vary the airfoil geometry with due regard to the aerodynamic and technical requirements. When modeling, displacements, stresses, and deformations were determined, which arisen in various operating modes with external loads. As a result of the research, computer models of a fragment of the mechatronic unit have been obtained, stresses and deformations under various loads have been determined, and recommendations for enhancing the efficiency of the structure under study have been developed. The dynamics of the damages indicates that the weakest element of the structure is the link in the place of bending. Also, stress risers were detected, which became the round parts of the segments. The results of the research can be used for designing and manufacturing configurable aircraft wing structures.
