“…Previous studies have proved that capturing vibration mechanical energy of track structures using various energy harvesters as power sources for wireless sensor networks is feasible (Bosso et al, 2021; Wang et al, 2015). Furthermore, the vibration energy of track structures is huge and stable (Wang et al, 2012), which is not limited by weather factors such as solar and wind (Hou et al, 2021; Wang et al, 2015; Yuan et al, 2014).…”

“…Wang et al (2014) developed a kind of piezoelectric circular membrane array to enhance the output power and widen the operating frequency bandwidth, which is expected to apply in the high speed rail systems. By combing the design concepts of the cymbal transducer and the multilayer stacks, Hou et al (2021) proposed a kind of piezoelectric vibration energy harvesters arranged in series with the steel-spring in the floating concrete slab, which are small and lightweight with high bearing capacity and excellent energy harvesting efficiency to utilize the vehicle induced steel-spring fulcrum forces. These achievements greatly promoted the development of energy harvesting techniques in railway systems.…”

Capturing vibration energy of track structures using piezoelectric energy harvesters has attracted increasing attention for powering wireless sensor networks along railway line. To better use the vertical space below steel rail, a kind of piezoelectric tube stack energy harvesters is proposed in this paper, which can be placed at the bottom of the steel rail to harvest the vibration energy of the vertical displacement induced by the moving train. The harvester consists of a displacement transmission rod, a compression spring, a force transmission metal tube, a piezoelectric tube stack, a whole metal shell, screw bolts, and a wire hole. The advantage of this design is to fully combine the heights of the compression spring, the force transmission metal tube and the piezoelectric tube stack, which helps reduce the vertical height of the device and enables its wide application to a variety of tracks, including, ballast track, ballastless track, and steel-spring floating slab track. Energy harvesting performance of the developed piezoelectric tube stack energy harvester is investigated experimentally, which is consistent with the theoretical results of the simplified model of such a harvester reported. Effects of displacement amplitude, displacement frequency, spring stiffness, resistance, and key parameters of piezoelectric tube stack on the energy harvesting performance of the harvester are also discussed. The present study provides a new design concept for developing piezoelectric energy harvesters used in railway systems with the smaller vertical space below steel rail.

“…Piezoelectric materials have been extensively used in many important industrial models and smart structures. [1][2][3][4][5][6] This is because of their effective electromechanical coupling properties as well as the capability of converting the main energy types, namely mechanical and electrical energies to each other. Consequently, a lot of articles were performed to investigate the behavior of these materials which made dealing with the functionally graded materials (FGMs) more reliable as stated by Wu and his coworkers.…”

In this article, thermal buckling analysis of multilayer functionally graded graphene platelets (FGGPL) strengthened piezoelectric beam subjected to external electric voltage as well as humid conditions is illustrated. The effective Young’s modulus of the nanocomposite beam is estimated within the framework of Halpin-Tsai model. While, Poisson’s ratio, mass density, and piezoelectric properties are calculated by the rule of the mixture. Four FGGPL distribution types are considered in this study. A refined two-unknown beam theory considering shear deformation as well as thickness stretching effect is employed to describe the displacement components. The principle of virtual work including thermal, moisture, and electric loads is used to derive the stability differential equations. To check the accuracy of the obtained buckling temperature, some comparison examples are performed. The impacts of the GPLs volume fraction, distribution type, length-to-depth ratio, humid conditions, external electric voltage, and piezoelectric properties on the critical buckling temperature are studied.
