摘要:
In a prediction of abrasion characteristic of a tire, a characteristic curve of a tire axis force generated on a tire rotation axis at the slip ratio applied to the tire and changed depending upon the slip ratio is acquired. From the characteristic curve, values of tire dynamic element parameters determining the characteristic curve are derived based on a tire dynamic model constituted by the tire dynamic element parameters. Furthermore, a tire sliding amount based on a sliding region, the sliding region and an adhesive region formed on the contact patch of the tire at the applied slip ratio are calculated by applying the values of the tire dynamic element parameters to the model. Lastly, an abrasion characteristic of a tread part of the tire at the applied slip ratio is predicted by using the tire sliding amount with abrasion characteristic data of a tread rubber of the tread part. According to the prediction results, a tire is designed and produced.
