Simple numerical calculation method of flow velocity on roof of train running in tunnel

open access: yesMechanical Engineering Journal, 2018
A pantograph mounted on a high-speed train roof is exposed to high-speed air flow while traveling, and lift force is generated in the pantograph. To ensure high current collecting performance of the pantograph, it is important to appropriately adjust the

More is less: Connectivity in fractal regions [PDF]

open access: yes, 2015
Ad-hoc networks are often deployed in regions with complicated boundaries. We show that if the boundary is modeled as a fractal, a network requiring line of sight connections has the counterintuitive property that increasing the number of nodes decreases

A simple analytical method for in-plane and out-of-plane coupled vibration of curved panels (Vibration analysis as combination of straight and curved beam coupled structure)

open access: yesNihon Kikai Gakkai ronbunshu, 2019
This paper presents an analytical method for in-plane and out-of-plane coupled vibration in thin curved panels. To treat such vibrations simply, a structure consisting of the combination of straight and curved beams is proposed and the connecting ...

Combining active structural damping and active suspension control in flexible bodied railway vehicles [PDF]

open access: yes, 2016
There is a desire to design lightweight railway vehicle bodies for future high speed trains. Previously, suppression of structural vibration of the flexible lightweight vehicle body was attempted via use of active suspensions (conventional actuators) or ...
