Method for predicting mechanical properties of tire under lateral deviation and longitudinal slip composite working conditions, application and computer program product

The invention belongs to the field of tire dynamic characteristics, and particularly relates to a method for predicting mechanical characteristics of a tire under lateral deviation and longitudinal slip composite working conditions, application and a computer program product. According to the method, the total shear force direction angle of the target tire is accurately corrected by adopting the reference tire information, so that the prediction accuracy of the longitudinal force and the lateral force of the tire under the composite working condition is remarkably improved. The lateral deviation and longitudinal slip composite working condition prediction data obtained through the method can replace lateral deviation and longitudinal slip composite working condition test data, and the method plays a very important role in improving the tire modeling efficiency and reducing the test cost. 本发明属于轮胎动力学特性领域，具体涉及一种侧偏纵滑复合工况轮胎力学特性预测方法、应用和计算机程序产品。该方法采用了参考胎信息对目标胎总切力方向角进行精准修正，使得复合工况下的轮胎纵向力及侧向力预测精度得到显著提升。该方法获得侧偏纵滑复合工况预测数
