ESTIMATION OF FATIGUE DURABILITY IN A ZONE OF A JOINT OF LOOPS OF FASTENING OF THE BACK LUGGAGE HATCH OF THE PASSENGER PLANE

Д О Бондаренко, К М Рудаков

Abstract


Modern aviation rules and other normative documents that regulate the order of providing of unconcern and economic efficiency of airplane for to the terms of tireless durability of construction produce the increased requirements to the volume and quality of calculations on the tiredness of basic elements of construction of glider of airplane. The resource of power construction of airplane is determined in this article – compartment of fuselage. For the estimation of tireless durability a FEM was used in the zone of joint of loop of hinge-plate of back luggage hatch. Methodology of determination of tireless descriptions of elements of construction of airplane was also described. 2 pictures of CAD of model of the examined zone and 5 pictures of FEM are presented in the article.

Keywords


fatigue; aircraft; coefficient of reliability; fuselage; fitting; longevity equivalent tension; main tension.
