Patent number: 10473556Abstract: 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.Type: GrantFiled: September 29, 2015Date of Patent: November 12, 2019Assignee: Kobe Steel, Ltd.Inventors: Toru Eguchi, Yoshiharu Nishida, Yoshiaki Matsubara, Yasuhiro Matsushita

Patent number: 9880074Abstract: A tire and a drum are relatively moved so that a pressing load is increased, and stopped when the pressing load becomes a predetermined value lower than a target value. A value of the pressing load and a relative distance between the tire and the drum are measured at timings when a circumferential position of the tire is the same. A dynamic longitudinal spring constant of the tire is calculated by using change amounts of the pressing load and the relative distance. An adjustment amount serving as a distance by which the tire and the drum are relatively moved so that a value of the pressing load when relative movement is stopped becomes the target value is calculated by using the dynamic longitudinal spring constant and a difference between the arrival value and the target value. The tire and the drum are relatively moved by the adjustment amount.Type: GrantFiled: December 8, 2015Date of Patent: January 30, 2018Assignee: Kobe Steel, Ltd.Inventors: Kohei Ito, Yasuhiro Matsushita
