Verification of Longitudinal Level Irregularity Suppression Effect at the Structural Boundary by Ballasted Ladder Track

Autor: Tsutomu Watanabe, Keiichi Goto, Kodai Matsuoka, Shintaro Minoura

Publikováno v: Applied Sciences, Vol 12, Iss 9, p 4150 (2022)

The ladder sleeper, which is a type of longitudinal sleeper with long beams in the longitudinal direction of the rail, was developed for the maintenance-labor saving of ballast tracks. In this study, to quantify the load distribution performance of t

Identification of Vibration Modes and Wave Propagation of Operational Rails by Multipoint Hammering and Reciprocity Theorem

Autor: Kodai Matsuoka, Kazuhiro Kajihara, Hirofumi Tanaka

Publikováno v: Materials, Vol 15, Iss 3, p 811 (2022)

Vertical bending vibration modes and rail wave propagation, including the damping characteristics, are the factors that cause rail corrugation. However, the ability to identify actual railways has been limited because of the huge number of sensors re

Experimental Validation of Non-Marker Simple Image Displacement Measurements for Railway Bridges

Autor: Kodai Matsuoka, Fumiaki Uehan, Hiroya Kusaka, Hikaru Tomonaga

Publikováno v: Applied Sciences, Vol 11, Iss 15, p 7032 (2021)

Simple bridge displacement measurement using a video camera is effective in realizing the efficient management of numerous railway structures via condition-based maintenance. Although non-marker image measurement is significantly influenced by the me
