中文摘要：

为了确定舰载机着舰过程中的动态变化,对美国航母上MARK7 Mod1型液压式舰载机阻拦系统开展研究,建立的阻拦系统的数学模型.利用Matlab对所建立的阻拦系统模型进行仿真分析,论述了着舰过程中阻拦系统和舰载机的动态变化,分析了液压装置和定长冲跑控制装置的在着舰过程中的作用.结果表明：利用MARK7 Mod1型阻拦系统,航母上的舰载机在一定的速度范围内着舰降落,都能够在固定的甲板长度内平稳的拦停,实现舰载机的安全着舰.

英文摘要：

To determine the dynamic movement of carrier-based aircraft landing,a type of MARK7 Mod1 hydraulic pressure arresting gear system on the US Navy aircraft carriers presently in service was studied.The mathematical model of this arresting system was built.Then a simulation model based on the arresting system＇s mathematical model was established,and simulation experiments based on Matlab were carried out.The emphasis of analysis was focused on the roles of the constant runout control device and hydraulic device.The result shows that the heaviest carrier-based aircraft in the US Navy aircraft carriers can be arrested on the flight deck at a constant distance when landing on the deck within a certain speed.
