【摘要】 飞机在自动着陆系统的引导下着陆时,在较为苛刻的条件下要求飞机减速制动并且安全着陆就需要有飞机拦阻器的辅助。并且希望着陆时的速度要快,时间要短。陆地飞机拦阻器就是一个能量转化器,将飞机着陆时所具有的庞大动能转化为其他能量形式。论文中讨论的陆地飞机拦阻器以美国BAK-12型飞机拦阻器为参考基础,飞机拦阻器的主要部件为对称布置在飞行跑道两侧的两个结构完全相同的能量转化器,其机械结构由几个较大的功能模块组成:拦阻索盘机构、传动机构、凸轮机构,还包括一些辅助机构和装置。本文在相关资料的基础上,在ADAMS软件中建立起了绳索模型,在AMESIM软件中建立了除拦阻索以外的系统拦阻模型,并通过AMESIM与ADAMS的联结接口进行了协同仿真,分析了拦阻索的张力波动对飞机的拦阻影响,并且能够分析飞机偏心拦阻情况。通过分析BAK-12型飞机拦阻器原理,再以原始设计参数为基础,在AMESIM软件中建立起了更为符合实际的拦阻仿真模型,分析了飞机在不同的质量、速度情况下,拦停过程中系统输出压力与飞机拦停时间关系。对个别飞机拦阻时,系统压力超过额定压力的情况采用模糊控制进行了修正,使其拦阻达到拦停要求。更多还原

【Abstract】 When aircraft lands on a harsher condition by the guidance of automatic landing system, it needs a auxiliary devices if it wants to retard brake and land safely. And the landing speed is fast and time is short. Aircraft arresting system is an energy conversion device, which converts large kinetic energy into other energy forms.American BAK-12 aircraft arresting device is taken as reference foundation in this paper. The aircraft arresting device’s major components are two energy converters with identical structure which symmetrical arranged on the both sides of the flight runway. The mechanical structure of the energy converter is composed of several big functional modules: the rope pulley organization, the transmission system, the cam gear, and it also contains some auxiliary mechanisms and devices.On the basis of some correlated data, a rope model is established in the ADAMS software environment, and the arresting system model besides of arresting rope set up in the AMESIM environment Through co-simulation between AMESIM and ADAMS, the model analyzes the impact of the aircraft arresting that caused by the tension waves of the rope, and the circumstance of the aircraft bias to runway center.Through analyzing of BAK-12 aircraft arresting principle, and then taking the primitive design variable as the foundation, a more realistic simulation model of arresting is established in AMESIM. The relationship between system output pressure and the aircraft stop time during the arresting process is analyzed under the condition of aircraft with different mass and speed. To specific aircraft, fuzzy control is carried out to revise the exceeded pressure so as to satisfy the requirement of the arresting.更多还原
