  • Patent number: 10473556
    Abstract: In a tire uniformity testing apparatus which measures uniformity of a tire by measuring a load applied to the tire pressed against a rotary drum, a load estimation model is generated which is used to control a pressing position of the rotary drum, and generates a load estimation model indicating a relation between the pressing position of the tire with respect to the rotary drum and the load applied to the tire. The load estimation model is generated by: holding the tire in which uniformity has already been measured for each characteristic value; acquiring a nominal model depending on the characteristic value of the tire; and generating based on the acquired nominal model.

  • Patent number: 10073000
    Abstract: In a rim replacing method for a tire testing machine of the present invention, one pair of the rims satisfying predetermined conditions relative to a test tire are selected, from among a pair of rims attached to the upper and lower spindles and plural pairs of rims loaded in a rim replacing device, as object rims, and rim replacement is performed if the rims loaded in the rim replacing device are selected as the object rims, so that the nonuniformity of rim can be suitably measured. The predetermined conditions include a condition in which a diameter of bead portions of the tire conveyed into the tire testing machine corresponds to a diameter of the object rims, and a condition in which a width of the bead portions of the tire conveyed into the tire testing machine falls within a range in which a space between the object rims is adjustable.

  • Patent number: 9360396
    Abstract: In a tire uniformity measurement, accurate tire uniformity is obtained from a measurement waveform immediately after a rotation of a tire is switched from a normal rotation direction to a reverse rotation direction. A tire uniformity testing device of the present invention includes a measurement unit 108 that obtains a force variation from a uniformity waveform corrected by a correction unit 109 that corrects the uniformity waveform so as to eliminate a shift gradient ? existing in the uniformity waveform measured after a rotation of a tire T1 is reversed, and further includes an air-outflow regulation member 220 that regulates an from flowing into a tire T2 when a drum 205 retreats or advances.
