To provide a wheel bench test device that identifies vibration characteristics of a wheel in a running state on a table.SOLUTION: A wheel bench test device includes a support 10 having a cylindrical bottomed hollow part, a circumferential groove 11 that continues in a circumferential direction so as to have a radial width in a part of a bottom surface of the hollow part, a wheel attachment shaft 13, a sensor device 14 that is arranged in the wheel attachment shaft and detects reactive force generated in the wheel, a magnet 15 that is arranged with a clearance in the circumferential groove while being attached to the wheel attachment shaft, a plurality of electromagnetic coils 16 that are arranged opposite to the magnet in the inside and the outside in a radial direction of the circumferential groove to generate rotation drive force of the wheel attachment shaft while holding a non-contact state in cooperation with the magnet, a drive control unit 18 that performs current control for the plurality of electromagnetic coils, and a controller 17 that controls the drive control unit while receiving measurement data of the sensor device. The controller controls the plurality of electromagnetic coils through the drive control unit to rotate the wheel, which is attached to the wheel attachment shaft and whose ground contact surface is brought into contact with a side wall surface, along the side wall surface.SELECTED DRAWING: Figure 1 【課題】走行状態の車輪の振動特性を台上にて同定する車輪台上試験装置を提供する。【解決手段】円筒形状で有底の中空部を有する支持体１０と、中空部の底面の一部に径方向に幅を有し周方向に連続する周溝１１と、車輪取付軸１３と、車輪取付軸に配置され車輪に発生する反力を検出するセンサ装置１４と、車輪取付軸に取り付け状態で周溝内に隙間をもって配置される磁石１５と、周溝に対して径方向の内側及び外側に磁石に対向配置され磁石と協働して非接触状態を保持しつつ車輪取付軸の回転駆動力を発生させる複数の電磁コイルと１６と、複数の電磁コイルへの電流制御を行う駆動制御ユニット１８と、駆動制御ユニットを制御し同時にセンサ装置の計測データを受信するコントローラ１７とを備え、コントローラは、駆動制御ユニットを通し複数の電磁コイルを制御して、車輪取付軸に取り付けられかつ接地面が側壁面に接地させた車輪を側壁面に沿って転動させる。【選択図】図１
