Abstract: An ultra-wideband electromagnetic band gap (EBG) structure includes multiple EBG units in an array. Each EBG unit includes a power plane, a dielectric substrate and a ground plane from top to bottom. The power plane includes a patch, a coupled complementary split ring resonator (C-CSRR) and a plurality of semi-improved Z-bridge structures. Each edge of the patch is provided with a semi-improved Z-bridge structure. The C-CSRR is provided within a ring formed by the semi-improved Z-bridge structures. The Z-bridge structure includes a first horizontal branch, a first vertical branch, a second horizontal branch and a second vertical branch connected in sequence. The second vertical branch is connected to the patch. First horizontal branches of adjacent EBG units are connected to each other. A circuit board including the aforementioned EBG structure is also provided.

Abstract: An energy absorption device configured to be provided at a front end of a train includes a coupler seat, a support base, a crush pipe, a coupler, a guide member, an energy absorption component and an anti-climbing assembly. The support base is fixedly arranged at the front end of the train; the crush pipe is fixed to the coupler seat; a connecting end of the coupler is inserted into the crush pipe and is slidable with respect to the crush pipe; the guide member has one end fixed to the coupler seat, and another end inserted into the support base and slidable with respect to the support base; the guide member limits an oscillation of the crush pipe; the energy absorption component is provided between the coupler seat and the support base; and the anti-climbing assembly is fixedly arranged on the support base and is compressible.

Abstract: A railway vehicle local multi-functional component includes a main body. The main body is an aluminum alloy profile, a reinforcing plate is provided on an outer surface of a bottom plate of the aluminum alloy profile as a vehicle lifting pad, built-in threaded seats are provided on an inner surface of the bottom plate of the aluminum alloy profile as a mounting seat for an anti-yaw damper of a bogie, and a through hole integrally formed with the aluminum alloy profile is provided in the aluminum alloy profile as a cable passage. Multifunction is realized by one structure, thus greatly simplifying the vehicle body local structure, and improving structural strength. A railway vehicle including the local multi-functional component is included.

Abstract: A chassis end plate assembly of a railway vehicle is provided, which includes an end plate; a bottom beam arranged at an inner side of a lower edge of the end plate, curved beams arranged at inner sides of two sides of the end plate, a buffer beam located above the end plate; and a reinforcing beam longitudinally arranged between the buffer beam and the bottom beam. The end plate assembly can increase the rigidity of an end portion of the vehicle and improve the vibration mode. The end plate assembly can be combined with an under-vehicle active device compartment so as to form an enclosed space, which may protect pipelines and devices under the vehicle. A railway vehicle provided with the chassis end plate assembly is further provided.
