摘要:
A car body (8) is supported on a bogie frame (4) through an air spring (5). Along the width direction of the car body (8), a torsion bar (11) is provided on the bogie frame (4). At both ends of the torsion bar (11), links (15) for inclining the car body (8), through levers (13) are provided. Accordingly, a rolling displacement of the car body is restricted and a vertical displacement is not restricted. Due to the inclined geometry of the levers (13) towards the center longitudinal plane of the car body (8), the car body is tilted in the proper direction when an excessive centrifugal acceleration occurs. An inclination device having a light weight structure, a good riding comfort, and a high failsafe characteristic can be obtained.
摘要:
The invention provides a state monitoring apparatus and a state monitoring method of a railway car, and a railway car capable of detecting or sensing a defect prior to the occurrence of a serious defect without having to set up thresholds corresponding to various traveling speed patterns. The railway car comprises a vibration detector for detecting a vibration of the railway car, and a defect detection system for detecting defect of the railway car using a signal output from the vibration detector, wherein the vibration detector includes a vibration detection means for detecting the vibration of the railway car from a vibration acceleration of the car body, and the defect detection system includes a filtering means for detecting two or more different frequency band components based on the car body vibration acceleration from the vibration detection means, an amplitude ratio computing means for computing an amplitude ratio of two or more car body vibration accelerations detected via the filtering means, and a defect determination processing means for determining defect based on the result of the amplitude ratio computing means.
