摘要：
A maximum entropy test method is proposed to evaluate the output reliability of space actuator with small sample size. According to the margin design characteristics of space actuator, the output force of the actuator is selected as the characteristic quantity to represent its output reliability. The output reliability is evaluated by experiment and calculation at critical operating points, and the evaluation process is introduced in detail. The results show that the proposed method can be used to evaluate high reliability (0.999 9 reliability with confidence of 0.95) with only a small number of test samples, and can significantly reduce the cost of production and test. The evaluated results are consistent and credible after recalculation by variables evaluation method. © 2022, Editorial Board of Acta Armamentarii. All right reserved.
