飞机无杆牵引安全技术研究

Aircraft Towbarless Traction Safety Technology

地面无杆牵引安全是民航业内关注的重点。在无杆牵引过程中,由于环境、人为因素可能引起牵引载荷过大而造成部件损坏,严重时导致机体受损。为了减少地面不安全事故发生,本文以TBL-180无杆牵引车和Boeing737-800客机为参考对象,基于CATIA软件建立相关三维模型,通过Simdesigner接口导入ADAMS-View平台,模拟牵引车启动、牵引车制动以及牵引车经过凹坑过程,从而探究对飞机下阻力臂载荷影响。仿真结果表明:牵引系统模型在不同情况下进行模拟仿真,通过仿真得到的下阻力臂载荷与理论分析的失效载荷形成对比,可进一步为地面牵引安全提供参考与意见。

Ground towbarless traction safety is the focus of the civil aviation industry.In the process of towbarless traction,due to environmental and human factors,the traction load may be too large to cause damage to the components,and in serious cases,the body may be damaged.To reduce the occurrence of ground unsafe accidents,the paper takes TBL-180 towbarless tractor and Boeing 737-800 passenger aircraft as reference objects,builds relevant 3D models based on CATIA,and imports ADAMS-View platform through Simdesigner interface to simulate tractor start and tractor system.The movement and the tractor pass through the pit process to explore the impact on the lower drag arm load of the aircraft.Simulation results show that the traction system model is simulated under different conditions.The simulation of the lower resistance arm load and the theoretical analysis of the failure load can provide some reference and opinions for the ground traction safety.
