Abstract:
Aiming at the difficulty of pyrovalve reliability validation and assessment, and requirement of large number of samples, a small sample reliability verification method of strenuous test is put forward. The product reliability is calculated with sample observation value by means of mathematical statistics method. Practical application proves that this method can obtain high reliability by using less test samples. It reduced the cost of reliability test, made the test evaluation possible and met the requirement of engineering reliability assessment of pyrovalve
