This paper presents a novel method for the fault detection and isolation for rail vehicle suspensions that explores the additional dynamic interactions between different motions of a bogie or body caused by the failure of suspension components by taking advantage of symmetrical mechanical configurations of railway bogies. The study is focused on the monitoring of the vertical primary suspension...

There have been numerous attempts and investigations carried out with the objective to reduce noise generated by railway freight wagons because is one of ever-present negative environmental pollution phenomena. This resulted in strong legislation requirements on reduction transport, case wagons, only exterior a problem. However, extremely hard metal structures running rails naturally generate h...

This study analyzes excessive vibrations that occurred on the railway vehicle bogie with computer simulation of a 4-DOF half car dynamic physical model and Euler-Bernoulli flexible bridge beam simply supported boundary conditions has been introduced considering some limitations which affect problem formulation. To reduce these other than conventional suspension systems such as passive one, an a...

Hunting; Rail wheelset; Hopf bifurcation; Discontinuous nonlinearity; Routh–Hurwitz criterion; Equivalent function; Analytical approach. Abstract This paper presents an investigation on bifurcation of railway bogie behavior in the presence of nonlinearities which are yaw damping forces in longitudinal suspension system and the friction creepage model of thewheel/rail contact including clearance...

This paper is concerned with the dynamic response of straddle-monorail single-axle bogie under curve condition. A 15 degrees-of-freedom(DOF) model established for straddle-type monorail vehicle bogie, which consists driving wheels, steering wheels and stabilizing wheels. The motion equations are derived using Lagrange's equation, wheel-rail contact curving track beam created. Compared test resu...

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...

Forestry machines are often travelling on unprepared terrain, which means often rather bumpy ride.4-wheeled machines became 6-wheeled and later on 8 wheeled machines to alleviate the worst obstacles. Nordic forestry people discovered if these wheels were arranged in bogie construction the machine (usually a forwarder that could carry timber) both could better negotiate obstacles and with all wh...
