Abstract/Summary:
Axles are one of the most important railway vehicle parts that supports the weight of both vehicle and passenger. Failure in Axle in its operating condition may cause heavy damage to the passenger and car as well, hence high strength design is required to mitigate the possibilities of axle failure. Generally steel axle is used in rail industry, nowadays there are more interest to replace steel axle to the composite axle. Use of advanced composite material such as Kevlar, graphite-fiber, carbon-fiber and glass-fiber with proper resin core resulted in remarkable achievements because of its specific strength and improve fatigue, specific modulus and reduction in energy requirements due to reduction in weight as compared to steel axle. This paper presents the modeling and analysis of metal composite rail axle using Epoxy carbon, resin Epoxy and 30NiCrMoV12. the overall objective of this paper is to analyze the metal composite axle to find out the best replacement for conventional steel axle in terms of reduced energy requirements reducing weight, comparing static behavior and the natural frequency of both conventional Rail Axle and Metal composite rail Axle when exposed to the same boundary and loading condition.it is also observed that compared to conventional material composite show lower stress and higher factor of safety.
