Research on Rail Safety Security System
This paper analysis the integrated use of safety monitoring with the domestic and international latest research on rail safety protection system, and focus on the implementation of an organic whole system, with the monitoring and early warning, risk assessment, predictive control and emergency rescue system. The system framework, contents and system structure of Security system is proposed comp...
متن کاملInvestigation of Wagon Derailment Moving on Random Rail Irregularities using Nonlinear 3-Dimentional Model (RESEARCH NOTE)
Rail irregularity is one of the most effective factors in train derailment. theste irregularities have generally random distribution that are assumed to be stationary random and ergodic processes in space, with Gaussian amplitude probabiliy densities and zero mean values. The quality of irregularities, their distribution along the rails and wagon speed are the main factors for train derailment ...

15 صفحه اولPreliminary results on dynamic analysis of a new test rig for wheel-rail contact studies
A new reduced–scale test rig is developed owing to significantly contribute to the applicability of the laboratory tests on rolling contact fatigue (RCF) in wheel-rail material. This paper introduces the dynamic analysis of the test rig, in order to assess the vibration behaviour of the system with respect to contact phenomenon. Finite element modelling (FEM) is used to simulate the mecha...
متن کاملResearch on Corneal Structure
A strong interplay between theory and experiment is a key feature in our continuing development of light scattering as a probe of corneal structure. A general theory for predicting scattering from the structures depicted in electron micrographs of abnormal corneas is reviewed, and an experimental test verifying that collagen fibrils are the primary scattering elements in the cornea is presented.
