摘要: Leveling railway vehicles, leveling secondary suspension systems, lift-systems for suspension systems, and other related systems and methods are shown and described. In one example, a railway vehicle includes a superstructure, a bogey, and a leveling secondary suspension system. The leveling suspension system includes at least one spring positioned between the superstructure and the bogey, and a secondary suspension-mounting lift system (SMLS) interfaced with coil spring. The SMLS includes a spring-mount (SM) and a piston assembly. In operation, pressurized hydraulic fluid acts on the piston and lifts the superstructure, thereby allowing the superstructure's access to be raised to a desired height, e.g. a platform height.

摘要: A dependence relation database (332) stores dependence relation information (33) wherein a dependence relation between each constituting apparatus among a plurality of constituting apparatuses, and an importance degree to represent intensity of the dependence relation are set, with a vehicle formation (10) being a vertex. An apparatus evaluation unit (302) calculates a soundness estimation value to represent soundness of a terminal constituting apparatus that does not have a constituting apparatus whereon the own constituting apparatus depends among the plurality of constituting apparatuses. A formation evaluation unit (303) acquires the dependence relation information (33), and by using a soundness estimation value of each constituting apparatus among the plurality of constituting apparatuses including the soundness estimation value of the terminal constituting apparatus, and an importance degree of the dependence relation, calculates a soundness estimation value in consideration of the importance degree of the dependence relation of an evaluation target apparatus that is a constituting apparatus being an evaluation target among the plurality of constituting apparatuses, which has a constituting apparatus whereon the own evaluation target apparatus depends.

摘要: The invention discloses a complex network-based high speed train system safety evaluation method. The method includes steps as follows: (1) constructing a network model of a physical structure of a high speed train system, and constructing a functional attribute degree of a node based on the network model; (2) extracting a functional attribute degree, a failure rate and mean time between failures of a component as an input quantity, conducting an SVM training using LIBSVM software; (3) conducting a weighted kNN-SVM judgment: an unclassifiable sample point is judged so as to obtain a safety level of the high speed train system. For a high speed train system having a complicated physical structure and operation conditions, the method can evaluate the degree of influences on system safety when a state of a component in the system changes. The experimental result shows that the algorithm has high accuracy and good practicality.

摘要: A sensing system includes a leading sensor, a trailing sensor, and a route examining unit. The leading sensor is onboard a first vehicle of a vehicle system that is traveling along a route. The leading sensor measures first characteristics of the route as the vehicle system moves along the route. The trailing sensor is disposed onboard a second vehicle of the vehicle system. The trailing sensor measures second characteristics of the route as the vehicle system moves along the route. The route examining unit is disposed onboard the vehicle system and receives the first characteristics of the route and the second characteristics of the route to compare the first characteristics with the second characteristics. The route examining unit also identifies a segment of the route as being damaged based on a comparison of the first characteristics with the second characteristics.
