  Abstract

  The railway industry seeks to increase the capacity of the railway system, providing flexibility to align capacity and demand, increasing availability, reliability and energy efficiency by reducing the life cycle cost (LCC), improving passenger comfort and increasing the attractiveness of rail transport. One of the lines of action to tackle the aforementioned challenges is the introduction of new lighter bodies and/or running gear structures, as both of these are among the heaviest components of the train. The potential weight savings (approximately 30 % and 50 %, respectively), and the use of new materials and processes in structures will result in reduced energy consumption, lower inertias, reduced track wear, and increased capacity to carry higher payloads. This article will present the development of a carbon fiber single axle running gear frame including design, calculation and testing, achieving a 50% reduction in weight while maintaining the performance of current steel structures. This project is within the Shift2Rail initiative, it is part of PIVOT and PIVOT2 Project. It has received funding from the European Union's Horizon 2020 program under grant agreements 777629 and 881807.

• Anti-buckling device for biaxial testing with cruciform specimens

  M. Moreno, S. Muñoz

  Materiales Compuestos (2022). Vol. 05 - Comunicaciones Matcomp19 (2021), (Núm. 2 - Caracterización analítica, numérica y experimental de los materiales compuestos. Materiales multifuncionales. Comportamiento de componentes estructurales.), 57

  
  

  Abstract

  The use of an anti-buckling device is proposed to avoid the appearance of undesired instabilities during biaxial testing with cruciform specimens in which the compressive loads are applied directly on the arms of the sample by means of compression plates. The device consists on a cross-shaped accessory that restricts out-of-plane displacements and a L-shaped support that forces the alignment of the fixture, the specimen and the testing machine. In addition, recommendations about the test methodology and the conditioning of the cruciform sample are given. For this purpose, analytical and numerical studies are developed to design the experiments and to describe both the global buckling of the cruciform specimen and the local instability of the central region subjected to biaxial loading. The risk of instability in the arms of the sample is reduced under tension-compression and compression-compression loading cases whenever the device is used, ensuring that the results are not affected by premature buckling of the specimen and favoring the appearance of appropriate failure modes.

• Damage detection in a fiber reinforced polymers based tower of a floating offshore wind and tidal power platform using structural dynamic parameters

  Abstract

  The development of offshore renewable energy structures is growing at a fast pace, and their maintenance will become critical in further years. Because steel corrosion on offshore structures is one of their highest maintenance cost, researchers are working to replace steel by Fibre Reinforced Polymers (FRP), due to their immunity to corrosion. This is done in the EU H2020 funded project FIBREGY, which also seeks improving maintenance costs by incorporating Structural Health Monitoring (SHM) strategies. A critical issue in SHM is the damage detection process, which is addressed in this paper. This study aims to characterize the dynamic behaviour of an offshore windmill FRP tower, and its evolution due the presence of structural damage. This analysis will be carried out using a Finite Element Model (FEM) of the structure, and the Serial-Parallel mixing theory to characterize the material performance. A sensitivity analysis of the changes in the dynamic response of the tower (frequencies and modal shapes) produced by structural damage is carried out. This analysis will provide the optimum design variables and objective functions required by a damage detection algorithm. The algorithm is optimization based, since it converts the damage detection problem into a mathematical one, and finds the best design variables to minimize the objective function. The algorithm is also model based, as it uses the structural model to obtain the objective function for the proposed design variables. Finally, this work presents the analysis of a potential damage scenario, in order to evaluate if the damage is effectively detected.
