Provided is a tire testing apparatus capable of accurately and easily measuring a load which a tire receives from a road surface. The tire testing apparatus includes a plate buried in a road surface with which a tire is in contact, at least one ground-contact-force sensor measuring a ground-contact force during a contact of the tire, and at least one plate sensor measuring a load applied to the plate. According to the tire testing device, a ground-contact force of the tire can be measured by the ground-contact-force sensor and a load which the tire applies to the plate can be measured by the plate sensor.

摘要:
A tire testing apparatus for testing a tire comprises a loading means for the tire (17), a measuring head (20, 22, 24) which is movable relative to the tire (17), and lower bearing elements (7) on which the tire (17) can be positioned in vertical position. To improve such tire testing apparatus, the tire testing apparatus comprises upper bearing elements (8) which are movable relative to the lower bearing elements (7) and which together with the lower bearing elements (7) form a holder for the tire (17).

摘要:
In the present invention, virtual regions each having a width of 1/2n (where n is a natural number greater than or equal to 1) of the detection width of a force sensor provided on a tire travel surface are set in a region to be measured of a tire. The contact position between the tire travel surface and tire is shifted along a prescribed direction such that the force sensor touches a single virtual region a plurality of times, and the sensor is used to carry out force measurement a plurality of times. Mapping data is generated that associates each measurement time with data about the positional relationship between the virtual regions and sensor. Force values for each virtual region are calculated on the basis of the sensor detection values and the force balance relationship between the sensor and virtual regions determined by a mapping data generation unit.
