To provide a lateral pressure calibration device and the like which can accurately calibrate the lateral pressure of a railway vehicle that is measured on a track side (ground side).SOLUTION: A lateral pressure calibration device 100 according to the present invention comprises: a device body 1 which is attached to a rail R and adds a vertical load toward a width direction center of the rail; and a jig 2 which is arranged between the device body and the rail. The device body comprises: a frame 11 which is attached to the rail; and load means 12 which is attached to the frame and adds the vertical load toward the width direction center of the rail. The jig comprises: a contact part 21 which is interposed between a lower part of the load means and a tread surface of a head of the rail, has a contact portion with the tread surface with a spot shape in the cross-sectional view, and vertically presses the tread surface by the vertical load added by the load means; and load measurement means 22 which measures the vertical load pressed by the contact part. The contact part can move in the width direction of the rail.SELECTED DRAWING: Figure 3
【課題】軌道側(地上側)で測定する鉄道車両の横圧を精度良く校正可能な横圧校正用装置等を提供する。【解決手段】本発明に係る横圧校正用装置100は、レールRに取り付けられ、レールの幅方向中央に向けて垂直荷重を付加する装置本体1と、装置本体とレールとの間に配置される治具2と、を備える。装置本体は、レールに取り付けられるフレーム11と、フレームに取り付けられ、レールの幅方向中央に向けて垂直荷重を付加する負荷手段12と、を具備する。治具は、負荷手段の下部とレールの頭部の踏面との間に介挿され、踏面との接触箇所が断面視点状であり、負荷手段が付加する垂直荷重によって踏面を垂直に押圧する接触部21と、接触部が押圧する垂直荷重を測定する荷重測定手段22と、を具備する。接触部は、レールの幅方向に移動可能である。【選択図】 図3
