Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] The determination of key systems of urban rail transit vehicles is judged by defining the criticality of each system, including the following steps:

[0018] S101. Classify the urban rail transit vehicle systems, and clarify the definitions and contents of each system;

[0019] Using the module division based on F-P(T)-B-S, from the perspective of considering the complex essential characteristics of urban rail vehicles, that is, from the functional characteristics, principle characteristics, behavioral characteristics and structural characteristics, etc., urban rail transit vehicles are divided into 9 types There are three systems, which are car body, car door, traction / electric brake, passenger information system, running part, air conditioner, air supply brake, train control and diagnosis system, and auxiliary system.

Abstract

The invention proposes a method for determining key systems of urban rail transit vehicles, which solves the problem of low comprehensiveness and low accuracy of key system determination in the prior art, and combines failure rate, failure severity, failure detection degree and maintenance cost , the comprehensive application of deterministic calculation and uncertain fuzzy evaluation improves the comprehensiveness and accuracy of key system determination, and helps to ensure the reliability and safe operation of vehicles to the greatest extent under limited conditions.

Description

technical field [0001] The invention belongs to the field of traffic safety engineering, and in particular relates to a method for determining key systems of urban rail transit vehicles. Background technique [0002] The operating environment of urban rail vehicles is closed and the passenger capacity is large. Once a traffic accident occurs, it will cause great inconvenience to the travel of passengers, and even cause huge loss of personnel and property. With the increase of urban rail transit lines and vehicles and the complexity of urban rail transit vehicles themselves, greater challenges have been brought to the maintenance of vehicles. Therefore, it is necessary to find scientific and effective calculation methods to judge the key systems of urban rail transit vehicles, and to ensure the reliability and operation safety of urban rail transit vehicles to the greatest extent under the existing resource conditions. At present, the methods commonly used to determine key s...
