Combined with the concept of intelligent tire, a tire condition monitoring system for predicting tire load information was designed, and a construction method of the tire load prediction model was proposed. Based on the finite element method, the construction process of tire load prediction model was explored. Under different inflation pressure and radial force, the tire deflection, the variation of tread height and tire cavity height in the grounding center area were obtained. Based on the above data, the tire radial stiffness fitting model and tread height variation fitting model were established. Finally, according to the theoretical formula of tire radial stiffness, the tire load prediction model was established and its validity was verified. The results show that the prediction model has high accuracy and can meet the requirements of use, which provides a theoretical basis for the development and design of tire condition monitoring system.

结合智能轮胎的概念，设计了一种预测轮胎载荷信息的轮胎状态监测系统，并提出了轮胎载荷预测模型的构建方法。基于有限元方法，探索了轮胎载荷预测模型的构建过程。在不同的充气压力和径向力下，得到了轮胎挠度、接地中心区域胎面高度和胎腔高度的变化。基于以上数据，建立了轮胎径向刚度拟合模型和胎面高度变化拟合模型。最后，根据轮胎径向刚度的理论公式，建立了轮胎载荷预测模型并验证了其有效性。结果表明，预测模型准确率高，能够满足使用要求，
