摘要
为了测量红外点源目标模拟器光轴相对五轴飞行仿真转台的三轴转台内框中心轴的偏差,建立了以转台内框中心轴为基准测试红外点源目标模拟器光轴位置的理论模型,分析了系统误差类型和测试原理,并设计了一套实验装置对红外点源目标模拟器光轴进行测试。该实验装置固定在三轴转台内框上,测量出红外点源目标模拟器光轴相对于转台内框中心轴偏离的角度,完成了目标光轴相对于转台内框中心轴的测试。实验装置测量角分辨率为0.2′,实验中测得目标光轴与转台内框中心轴的角偏差为1.0′。
In order to measure the error between the optical axis of infrared point source target simulator and the inner frame′s central axis of three-axis turntable of five-axis flight motion simulator,a theoretical model was established to test the position of infrared point source target optical axis.The varieties of systematic errors and the testing principles were analyzed and a experimental device used to test the optical axis of infrared point source target simulator was designed.The experimental device which was fixed on the inner frame of three-axis turntable could measure the angle of the optical axis of infrared point source target simulator relative to the inner frame′s central axis of turntable,thus it was able to carry out testing of the optical axis relative to the inner frame′s central axis of turntable.The precision of measuring angle is 0.2′.Through the experiment,the angle of the optical axis of target and the inner frame′s central axis of turntable is 1.0′.
