摘　　要：在对无人机等设备开展环境及可靠性试验时,为模拟其飞行姿态设计了一种无人机飞行姿态模拟器(二维转台)。首先,介绍了飞行姿态模拟器的关键零部件选型;然后,为使飞行姿态模拟器满足无人机相关试验要求,通过有限单元法对其进行静力学分析及模态分析,并研究转动零部件的等效建模方法;最后,计算结果显示:飞行姿态模拟器在重力作用下的最大变形量为0.298 mm,整体结构的基频为16.6 Hz,模态振型为绕底座轴扭转。仿真结果表明:飞行姿态模拟器设计合理,能满足试验需求。To better simulate the flight attitude of the UAVs when carrying out ETS（Environment test simulation）and reliability tests on UAVs and other equipment,a UAV flight attitude simulator（Two-dimensional turntable）was designed.First,the selection of key parts in the two-dimensional turntable are introduced in consideration of the harsh environment of the ETS.Then,the equivalent modeling method of the rotating parts are studied,besides,the static structural and modal of the turntable are analyzed with FEM method in order to make the two-dimensional turntable meet the test conditions.The results shows that the maximum deformation of the turntable under gravity is 0.298 mm,the fundamental frequency of the whole structure is 16.6 Hz,which shows that the flight attitude simulator is reasonable in design and meet the test requirements.
