To provide a lateral pressure measurement device and the like with improved accuracy of lateral pressure measurement.SOLUTION: A lateral pressure measurement device measures a lateral pressure Q between a wheel 100 of a railway vehicle and a rail. The wheel includes a rim part 110 provided on an outer peripheral part and formed with a tread, a boss part 120 provided in a center part and mounted with an axle, and a plate part 130 provided between the rim part and the boss part. The lateral pressure measurement device includes: a plurality of strain gauges, which passes through the plate part in a rotation center axis direction of the wheel and is attached to an inner surface of a hole whose angle position around the rotation center axis is arranged in a range within π/4 rad so as to detect shear strain of the plate part due to the lateral pressure; and a lateral pressure calculation unit for calculating the lateral pressure based on the output of a bridge circuit constituted of the strain gauges.SELECTED DRAWING: Figure 2
【課題】横圧の測定精度を向上した横圧測定装置等を提供する。【解決手段】鉄道車両の車輪100とレールとの間の横圧Qを測定する横圧測定装置を、車輪は、外周縁部に設けられ踏面が形成されたリム部110と、中央部に設けられ車軸が取り付けられるボス部120と、リム部とボス部との間に設けられた板部130とを有し、横圧測定装置は、板部を車輪の回転中心軸方向に貫通するとともに回転中心軸回りにおける角度位置がπ/4rad以内の範囲に配置された孔の内面に貼付され横圧に起因する板部のせん断ひずみを検出する複数のひずみゲージと、前記ひずみゲージで構成されたブリッジ回路の出力に基づいて横圧を算出する横圧算出部とを備える構成とする。【選択図】図2
