“…In a numerical study on the joints, Kim et al 45 used the finite element method and sub‐modeling technique to optimize the mechanical properties of bolted joints in their developed composite bogies. In another study on the same composite bogie design, the behavior of adhesively bonded T‐joints in the bogie frame was evaluated 46,47 …”

“…In another study on the same composite bogie design, the behavior of adhesively bonded T-joints in the bogie frame was evaluated. 46,47 Besides the detailed designs of connections and joints, some investigations on the possible reinforcing methods have been recently performed to enhance the durability and performance of the composite bogies. In this context, Liu et al 48 introduced the design strategy of thin-ply on the composite bolster of a bogie system.…”

The application of fiber‐reinforced polymer (FRP) composite materials and structures in various industrial sectors is expanding significantly to meet the rising demand for efficient, reliable, and functional building materials. Using FRPs can be an excellent strategy for enhancing railway structures and equipment because of their high strength‐to‐weight ratio, tailorable mechanical properties, and suitable long‐term characteristics. However, the railway industry appears to be hesitant to adopt composite materials compared to other transportation sectors like aerospace. It seems that there is still a long way to go before FRPs reach their full potential in railway applications. The goal of the current study is to explore the current uses of FRPs in the railway industry and the significant challenges, obstacles and difficulties that must be overcome to put FRP‐based concepts into practice for structural and rail vehicle applications.Highlights Applications of FRPs in railway vehicles and rail lines are reviewed. Main challenges for utilization of FRP in railway industry are studied. Future trends and applications of FRPs in the railway sector are introduced.

“…The shapes of bogies as well as the load conditions, such as static load and dynamic load, are complex. Therefore, various tests including static load tests, fatigue tests, and track tests are required for the design and the strength evaluation of the bogie [1][2][3][4]. The bogie frame is required to last 25 years or longer as the main structure that supports loads of the vehicle body.…”

The bogie frame of a railway is an important structural member for the support of vehicle loading. In general, more than 25 years’ durability is necessary. Much study has been carried out in experimental and theoretical domains on the prediction of the structural integrity of the bogie frame. The objective of this paper is to estimate the structural integrity of the bogie frame of an electric railcar. Strength analysis has been performed by finite element analysis. From this analysis, stress concentration areas were investigated. To evaluate the loading conditions, dynamic stress was measured by strain gauge. It has been found that the stress and strain due to the applied loads were multiaxial conditions according to the location of the strain gauge. Fatigue strength evaluations of the bogie frame were performed to investigate the effect of a multiaxial load through the employment of a critical plane approach.
