Investigating on the Effects of Random Irregularities of Railway Track by Half-Bogie Model
The vibrations produced by trains include two parts which are deterministic and random vibrations. Due to variation of dynamic loads and patterns of load-time, the random vibration of moving train is one of the most important issues in the field of railway engineering. One of the important sources in producing the train vibrations is rail roughness and irregularities. In this paper, responses o...
متن کاملTrack 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 کاملRisk Evaluation of Bogie System Based on Extension Theory and Entropy Weight Method
A bogie system is the key equipment of railway vehicles. Rigorous practical evaluation of bogies is still a challenge. Presently, there is overreliance on part-specific experiments in practice. In the present work, a risk evaluation index system of a bogie system has been established based on the inspection data and experts' evaluation. Then, considering quantitative and qualitative aspects, th...
