This paper presents a probabilistic load model for fatigue assessment of old metallic railway bridges. The traffic basis of the model consists of trains obtained from past records and present-day trains obtained from codes. The traffic is divided into four distinct time periods each associated with particular characteristics in rail traffic. Traffic evolution scenarios for the future, in terms ...

The objective of this paper is to present review on the axle used in railways to have better performance with minimum losses to railways . There are various material which is used for manufacturing axle. This paper gives the summary and range of various material used in the railway axle and our aim is to find stresses on axle and is to reduce the maintainence cost stresses as well as increase t...

This paper provides a hierarchical control strategy for cooperative braking system of an electric vehicle with separated driven axles. Two layers are defined: the top layer is used to optimize the braking stability based on two sliding mode control strategies, namely, the interaxle control mode and signal-axle control strategies; the interaxle control strategy generates the ideal braking force ...

Usually, vehicles driven under diierent road conditions are subjected to various forces and moments. An uneven input force originating from road surface could be one of the major load aaecting ride comfort or body vibration. In order to investigate the ride and handling characteristics of a tandem axle truck, a three dimensional mathematical model is developed, and the equations of motion for t...

Probabilistic assessment on the code-specified impact factors of RC decks is investigated by means of a three-dimensional traffic-induced dynamic response analysis of bridges combined with the Monte Carlo simulation technique. The random variables considered in the simulation are the roadway roughness, bump height, traveling position of vehicles, vehicle running speed and axle load of three-axl...

An articulated lorry was instrumented in order to measure its performance in straight-line braking. The trailer was fitted with two interchangeable tandem axle sub–chassis, one with an air suspension and the other with a steel monoleaf 4–spring suspension. The brakes were only applied to the trailer axles, which were fitted with anti–lock braking systems (ABS), with the brake torque controlled ...
