タイヤ剛性試験方法
Document Type and Number:
Japanese Patent JP6743535
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a tire rigidity test method for accurately evaluating the rigidity of a pneumatic tire.SOLUTION: A tire rigidity test method using an assembly 1 consisting of a wheel 3 having a rim part 3a and a pneumatic tire 4 mounted on the rim part 3a and controlled in a regular internal pressure comprises: an attaching step S2 of attaching the wheel 3 of the assembly 1 to the support shaft 5 of a rigid tester 2; a pressing step S3 of relatively moving the support shaft 5 toward a table 6 to press the pneumatic tire 4 of the assembly 1 against the table 6; a displacement applying step S4 of relatively displacing the table 6 pressing the pneumatic tire 4; a measurement step S5 of measuring a load F acting on the table 6 and a distance L between the table 6 and the rim part 3a; and a calculation step of calculating the rigidity of the pneumatic tire 4 from the measured load F and distance L.SELECTED DRAWING: Figure 1
