The present invention relates to a tire stiffness measuring device, and more specifically, to a tire stiffness measuring device for measuring a point-scale stiffness of a tire. A tire stiffness measuring device according to an embodiment of the present invention comprises a tire driving unit for moving a tire mounted and fixed to a main axle, a stiffness measuring unit configured to move toward the tire moved from the tire driving unit and make point contact with the tire surface, and measuring stiffness from the degree of displacement to a load by using a load cell measuring the load applied to the tire and a distance sensor measuring the distance from the tire, and a position measuring sensor for measuring the position at which the stiffness measuring unit makes contact with the tire surface.

    본 발명은 타이어 강성 측정장치에 관한 것으로, 보다 상세하게는 타이어의 점 단위 강성을 측정하기 위한 타이어 강성 측정장치에 관한 것이다. 본 발명의 일 실시예에 따른 타이어 강성측정장치는, 메인축에 장착 및 고정된 타이어를 이동시키는 타이어 구동부와, 상기 타이어 구동부로부터 이동된 타이어를 향해 이동하여 타이어 표면에 점접촉하도록 구성되고, 타이어에 가해지는 하중을 측정하는 로드셀과, 상기 타이어와의 거리를 측정하는 거리센서를 통해 하중에 대한 변위 정도로부터 강성을 측정하는 강성측정부 및 상기 강성측정부가 타이어 표면과 접촉되는 위치를 측정하는 위치측정센서를 포함한다.
