Optimisation and Management of Energy Generated by a Multifunctional MFC-Integrated Composite Chassis for Rail Vehicles

Abstract: With the advancing trend towards lighter and faster rail transport, there is an increasing interest in integrating composite and advanced multifunctional materials in order to infuse smart sensing and monitoring, energy harvesting and wireless capabilities within the otherwise purely mechanical rail structures and the infrastructure. This paper presents a holistic multiphysics numerical study, across both mechanical and electrical domains, that describes an innovative technique of harvesting energy from a piez… Show more

“…To achieve a design optimized for sensor performance and benefits, parametric studies need to be conducted through theoretical investigation [128,129] including multiphysics and multiscale numerical simulation. [130][131][132] Improving modeling accuracy could remarkably increase the efficiency of the structural optimization of computational interactions between mechanical and electromagnetic fields, thereby reducing the time and cost of manufacturing and tooling in experiments. At the same time, such enhancement would also help to determine the microscale/nanoscale mechanisms impacting both mechanical and electromagnetic behavior of the functional piezoelectric and magnetostrictive materials.…”

“…With the development of low-energy electronic products such as integrated circuits, MEMS, and microsensors, there are many drawbacks to energy harvesting and storage methods, including their high cost, large size, and the requirement to replace them frequently [ 1 , 2 , 3 , 4 ]. Therefore, there is an urgent need for a sustainable energy supply.…”

“…Lightweight design of railway vehicles is applied to conserve energy; however, using light materials and adopting a lightweight structural design may also result in deterioration of rigidity of the vehicle body [23,24]. This reduction could result in low modal frequencies and strong vibrations, impacting vehicle stability and passenger comfort.…”
