摘要： Improved and more easily implemented methods for predicting high speed radial force variation and uneven mass distribution utilize other measurements such as radial nm out and other parameters. The prediction model for high speed radial force variation uses a speed-dependent calibration term for predicting higher harmonic components, while the same or other models can be used for the first harmonic. The uneven mass distribution prediction model accounts for deformation of the tire along multiple tracks, thus employing a more realistic model of crown deformation that accounts for changing tire stiffness levels across different harmonic components of the measured and predicted parameters.

摘要： Boundary lines which are contours of uneven marks are detected in a sample original image of the sidewall surface of a sample tyre, and a mask image showing the position of the boundary lines is generated. Thereupon, a height offset image which shows a height of the uneven marks is generated by, in use of a plurality of discrete height threshold values, classifying the height of regions in the sample original image which remain after excluding regions corresponding to the positions of the boundary lines shown in the mask image. An unevenness-excluded image is generated by excluding the uneven marks from an inspection image of a sidewall surface of a tyre under inspection, by subtracting the height offset image from the inspection image. A shape defect in the sidewall surface of the tyre under inspection is inspected on the basis of the unevenness-excluded image.

Alternatively or additionally, the control and display device (40) has at least one display panel (44, 45, 46, 47) which can be used to display the coordinates of the position of the measuring head (20). The coordinates are determined using a coordinate system whose origin (0) is at the point of intersection of the tire plane (RME, RME1, RME2, MBE) and a roll axis (R) which extends through the center (M) of the tire (10) in the axial direction (z).

摘要： Repeated small irregularity, i.e. defect in outer shape on a sidewall portion S of a pneumatic tire T is detected. An order analysis is performed in higher order by an order analysis means 24 based on a waveform measured the irregularity on the sidewall portion S of the pneumatic tire T along the circumferential direction to calculate the value of the small irregularity at this order, and then the defect in outer shape is decided if the value of the small irregularity exceeds an allowable value. Thus, a pneumatic tire T of which small irregularity of certain order exceeding the allowable value is repeatedly formed in the circumferential direction on the sidewall portion S can be easily and certainly rejected as a defective tire.

摘要： A tire shape measuring system measures a surface shape on the basis of an image of a line of light (a light section line) emitted to a surface of a relatively rotating tire using a light-section method. The shape measuring system includes a light projector for emitting a plurality of lines of light onto a tire surface in directions different from a direction in which the height of the surface is detected so as to form a plurality of separate light section lines and a camera for capturing images of the light section lines in directions in which chief rays of the lines of light are specularly reflected by the tire surface. The shape measuring system individually detects the coordinates of the light section lines from images of pre-defined independent image processing target areas for each captured image and calculates the distribution of the surface height using the detected coordinates.
