Track Side Bogie Monitoring System
Introduction: Indian Railways at present does not use any automated system for real-time online monitoring of the performance of bogies and wheel-sets. Bogies are checked only during TXR examination for loose or broken parts. Wheel sets are changed when they reach the condemning limit. Problems like skew ness in bogie or asymmetric wheel-wear are attended to during preventive maintenance schedu...
متن کاملThe Experiment Study for Fatigue Strength of Bogie Frame of Beijing Subway Vehicle Under Overload Situation
In this paper, a problem for safety of bogie frame of subway vehicle under overload situation has been discussed. Firstly, the structure of bogie frame and service condition are introduced to explain the reason caused fatigue failure. Then, the testing points are selected in terms of the structure of bogie frame, the characteristics of processing technique, load transfer path and the operation ...

متن کاملModeling Steel Frame Buildings in Three Dimensions. II: Elastofiber Beam Element and Examples
This is the second of two papers describing a procedure for the three-dimensional nonlinear time-history analysis of steelframed buildings. An overview of the procedure and the theory for the panel zone element and the plastic hinge beam element are presented in part I. In this paper, the theory for an efficient new element for modeling beams and columns in steel frames called the elastofiber e...
متن کاملTHREE SCHEMES FOR ACTIVE CONTROL OF THE PLANAR FRAME
Optimal locations of the actuators for frame active control are investigated in this article. The aim is to minimize the structural drifts by employing several actuators. By utilizing genetic algorithm, the appropriate locations of the actuators are determined. They should be placed in locations where they can minimize the maximum structural drift. To explore the capability of the proposed tech...
