针对摆动扫描式红外地球敏感器，文章提出了一种长寿命试验测试方法.设计摆动频率为55~60 Hz的加速摆动扫描机构模拟件，在正弦驱动信号的激励下产生本征频率附近的摆动，实现红外地球敏感器摆动扫描机构的加速寿命试验；并研制了试验平台，实时记录和分析试验参数.试验结果表明：长寿命试验摆动扫描机构模拟件在窄扫模式时，摆动次数累计1.4×109次，摆动频率和电压峰-峰值的标准差分别小于0.0020Hz、0.0309 V

To test the life and reliability of swing scanning-type infrared earth sensors, an accelerated life test method is proposed. A sample set for simulating the swing scanning unit is designed, with swing frequency of 55~60 Hz. The stable amplitude oscillation is generated by a sine driving signal. A special test platform is developed, to record and analyze the test data automatically. The test results show that the standard deviation of the swing frequency is less than 0.002 0 Hz, and the standard deviation of the peak-to-peak voltage is less than 0.030 9 V.
