Abstract

The invention relates to a railway wagon curve passage performance reliability evaluation method and device, a computer device, a system and a storage medium. The method comprises the following steps of acquiring the curve passing performance ground monitoring data of a target type of railway wagon in a regular checking period; obtaining the regular checking information of the target type of railway wagons; matching the curve passing performance ground monitoring data and the regular checking information of the target type of rail wagon according to the train numbers, and obtaining the curve passing performance data and the corresponding operation time of each rail wagon; performing curve passing performance failure evaluation according to the curve passing performance data of each rail wagon to obtain a curve passing performance reliability sample of the target type of rail wagon; and performing reliability evaluation through the performance reliability sample according to the curve to obtain a reliability index of the target type of railway wagon. By adopting the method, the reliability of the curve passing performance of the railway wagons of the target type can be accurately evaluated.

Description

technical field [0001] The present application relates to the technical field of reliability evaluation, in particular to a reliability evaluation method, device, computer equipment, system and storage medium for railway freight car curve passing performance. Background technique [0002] Railway wagon is a typical mechanical system. When running at high speed on a curved road section, it is easy to cause derailment accidents due to insufficient curve passing performance. Therefore, the reliability evaluation of curve passing performance is of great significance to the operation safety, design, manufacture, maintenance cycle and standard specification of railway trains. However, the reliability evaluation of the curve passing performance of traditional railway wagons is carried out through the vehicle curve passing performance test. Due to the small number of samples evaluated, unstable results, and high costs, it is impossible to accurately evaluate the reliability of the c...
