To solve a problem such that it is difficult to measure vibration characteristics of a tire wheel in an intermediate frequency band of 300 Hz and over in a conventional tire table test device.SOLUTION: A tire table test device 10 mainly includes: a base plate 11; axle fixing equipment 12 fixed to the base plate 11; grounding equipment 14 for applying a desired load to a tire 22 fixed to the axle fixing equipment 12; and a fixing member 15 for fixing the grounding equipment 14 to the base plate 11. With this structure, the grounding equipment 14 contacts the tire 22 at a contact surface of various angles and is securely fixed to the base plate 11 at the fixing member 15. When vibration characteristics of a tire wheel 21 are measured, it is possible to prevent resonance of the tire table test device 10 and the tire wheel 21 to measure vibration characteristics of the tire wheel including an intermediate frequency band of 300 Hz and over.SELECTED DRAWING: Figure 3
【課題】従来のタイヤ台上試験装置では、300Hz~の中周波帯域でのタイヤホイールの振動特性を計測し難いという課題があった。【解決手段】本発明のタイヤ台上試験装置10では、主に、定盤11と、定盤11に固定される車軸固定器具12と、車軸固定器具12に固定されたタイヤ22に所望の荷重を加える接地器具14と、接地器具14を定盤11へと固定する固定部材15と、を備える。この構造により、接地器具14は、様々な角度の接触面にてタイヤ22と接触すると共に、固定部材15にて定盤11へとしっかりと固定される。そして、タイヤホイール21の振動特性を計測する際に、タイヤ台上試験装置10とタイヤホイール21との共振を防止し、300Hz~の中周波帯域を含めたタイヤホイールの振動特性計測を行うことができる。【選択図】図3
