Method for arranging falling impact load resisting safety belt mooring connectors of high T-tail

一种高t尾翼抗坠落冲击载荷保险系留接头布置的方法

Abstract

本发明公开了一种高T尾翼抗坠落冲击载荷保险系留接头布置的方法,包括以下步骤:A根据平尾结构的翼展及肋的布置,并结合冲击载荷原理及保险带相关国家标准和力学性能,准确评估接头所承受的坠落冲击载荷;B根据步骤A获得的载荷数据对接头的个数进行合理的布置;C根据保险带接头的尺寸以保证保险带接头容易挂上,最大限度的降低系留接头的开孔尺寸,并尽量降低接头截面尺寸以降低接头重量;D采用catia进行建模,考虑连接、倒角和倒圆等细节设计;E采用PATRAN进行有限元模型的建立并进行优化分析。本方法涉及的保险系留接头布置能有效提高飞机的维护性和保障维护人员的生命安全以及预防结构的损伤。
The invention discloses a method for arranging falling impact load resisting safety belt mooring connectors of a high T-tail. The method includes the following steps that A, falling impact loads borne by the connectors are accurately evaluated according to the arrangement of a wingspan and ribs of a horizontal tail structure in combination with an impulse load principle as well as Chinese national standards and mechanical properties related to a safety belt; B, the number of the connectors is reasonably set according to load data obtained in the step A; C, the effect that the safety belt is easily hung on the safety belt connectors is guaranteed according to the sizes of the safety belt connectors, the sizes of holes of the mooring connectors are reduced to the maximum degree, and the sectional dimensions of the connectors are reduced as much as possible so as to reduce the weight of the connectors; D, catia is used for modeling, and detail design such as connection, chamfering and rounding is considered; and E, PATRAN is used for building a finite element model and conducting optimization analysis. The safety belt mooring connector arrangement involved in the method can effectively improve the maintainability of an airplane, guarantee the life safety of maintenance personnel and prevent structural damage.
