static analysis of railway overheads considering pantograph effect
Authors
abstract
this article is concerned with the static analysis of structural cables used in railway overheads. structural analysis computer program named ansys is used for analysis. two effects are considered in the analysis. first one is the bending behavior effect of cables. beam188 in addition to link10 and link180 is used to see the difference in case of additional bending effect. besides, link10 and link180 is also compared. second one is the effect of pantograph. pantograph is modelled as a contact element instead of a force. accordingly, some sample cable systems similar to railway overhead are analyzed.

full textAnalyzing Efficiency of Railway Transportation by Considering Quality of Services: New Data Envelopment Analysis Models
Many studies have been conducted to analyze efficiency of railways for different countries. However, these studies have mainly focused on quantitative aspects of railway transportation and quality has been neglected. In this paper three new data envelopment analysis (DEA) models are presented. The first model is solved for assessing quality of passenger railway services in 71 countries of t...
full textStatic and Dynamic Analysis of Railway Track Sleeper
The increased speed and weight of modern trains puts the components of a railway track in a highly dynamic load situation. Irregularities of the wheels and rails induce substantial dynamic loads that have to be accounted for in the procedure of designing the railway track. The concrete sleeper is an essential part of the track structure and there is a growing demand for improved analytical tool...
full textConsidering Uncertain Communication Overheads in Probabilistic Loop Scheduling
This paper presents a new methodology for statically scheduling a cyclic dataow graph whose node computation times can be represented by random variables. A communication cost issue is also considered as another uncertain factor in which each node from the graph can produce di erent amount of data depending on the probability of its computation time. Since such communication costs rely on the a...
full textEmpirical analysis of overheads in cluster environments
In concurrent computing environments based on heterogeneous processing elements interconnected by general-purpose networks, several classes of overheads contribute to lowered performance. The most obvious limitations are network throughput and latency, but certain other factors also play a significant role. In an attempt to gain some insight into the nature of these overheads, and to propose st...
