摘　　要：系留气球是一种依靠气囊内的浮升气体获得浮力,并用缆索拴系固定的浮空器。系留气球、三根机械拉索、地面转动梁等构成系留气球三拉索收放系统,综合考虑收放系统中三拉索的运动特性,采用Matlab/Sim-ulink工具对近地三拉索收放运动进行系统建模,建立了整体的三拉索收放运动状态的仿真模型,仿真结果表明:仿真计算结果与实际飞行测量数据符合度好,结果比较合理。因此,仿真模型的建立为气球系统设计与放飞操作提供依据。A tethered balloon is a kind of aerostat,which is filled with low-density gas in its gasbag,and is fastened with cable.The launch and recovery system with three guy cables of tethered aerostat includes tethered aerostat,three guy cables and rotational girder on ground.Considering the movement characteristic of the guy cables in the launch and recovery system,the model on the launch and recovery motion states of three guy cables is established in this article.The system modeling is established by using software Matlab/Simulink.The curve of the simulation result shows：the simulation result agrees with the flight test data well,the result is reasonable.So the establishment of the simulation will provide support for the design of tethered aerostat system and the flying operation.
