Decision and Verification on Reliability Index of PSD in Rail Transit
Abstract: Aiming at the conditions that PSD (platform screen door) lacks quantitative analysis and verifica-tion of reliability in traditional design, the test method of goodness-of-fit index of life and the pro-cedure determining reliability model of PSD are studied; the way determining quantitative indi-cators of reliability is put forward; the influence of reliability verification results on the number of failure and the level of confidence is analyzed; accordingly the reliability anticipation of PSD at a special time and a special condition is given out. The research shows that the reliability of PSD has much to do with its use frequency. During the engineering design, the reliability of PSD and the failure rate of every PSD should be determinated according to its using characteristic.
