飞机轮载作用下的甲板动响应

本文从工程应用的角度出发，提出了一个逆求飞机起落架系统非线性动力特性的方法，并将飞机起落架系统以及在波浪运动的船体国反结构看作一个耦合的动力学系统，建立了一套着舰飞机与甲板瞬态相互作用的动力学分析方法，用该方法可以预报在各种海况，航速及机降工况下舰船甲板的动应及飞机承受的冲击过截，本文给出了计算例子。

DYNAMIC RESPONSE OF FLYING DECK TO AIRCRAFT LANDING LOADS

An engineering approach is introduced to evaluate the dynamic interaction behavior between the landing aircraft and the flying deck of a surface ship. Presented is a retroactive method for obtaining the non-linear dynamic characteristics of the landing gear system from the data recorded during the landing or dropping test on the rigid surface. The aircraft with its landing gear and the fling (landing) deck as a part of the deformable structure of the ship hull responding to waves, is considered as coupled dynamic system. A dynamic analysis method is proposed to solve the transient interaction of the coupled system.The present method may be employed to predict the dynamic overload encountered by the aircraft during different landing operations with the ship responding to different sea states and forward speed. The numerical examples are also illustrated.
