民用飞机地面载荷动态设计方法

Dynamic Design Method of Ground Loads of Civil Aircraft

为解决民用飞机地面载荷动态响应设计问题,文中根据适航规章CCAR25部,提出了一种民用飞机地面载荷动响应分析方法。利用Adams软件与Nastran软件,仿真弹性飞机着陆与滑行动载荷,计算全机动态响应,并计算全机地面载荷包线,结果用于强度设计。这一方法分析已应用于某民用飞机的载荷设计中。

In order to solve the problem of dynamic response of civil aircraft ground load,this paper proposes a dynamic response analysis method for civil aircraft ground load based on the airworthiness regulation CCAR25.Adams software and Nastran software were used to simulate the dynamic loads of landing and taxiing,then the ground load envelop of the whole aircraft was calculated,which can be used for strength design.This method has been applied to the load design of a certain civil aircraft.
