Research Progress on Prediction of Force and Moment Characteristics of Automobile Tire

回顾汽车轮胎六分力测试技术和汽车轮胎模型及预测研究的发展,介绍和评述了轮胎六分力的建模方法和预测机理,总结了轮胎六分力特性预测的核心问题和发展方向。不同负荷条件下的轮胎纯侧偏或纯纵滑六分力特性预测,以及基于纯工况试验数据预测复合滑移特性已经取得一些研究成果,但模型预测范围和精度均有待提升;具有预测能力的轮胎模型可减少试验量,在产品开发效率和成本控制上均具有应用前景;高精度、高计算效率和低成本、短周期,以及可反映设计参数变化的轮胎模型研究是模型发展的重要方向。

The development of automobile tire force and moment test technology,tire model and force prediction research were reviewed,the modeling method and prediction mechanism of tire force and moment were introduced,and the core problems and development direction of tire force and moment characteristic prediction were summarized.Some research results were achieved on the prediction of pure side slip or pure longitudinal slip force and moment characteristics under different load conditions,and on the prediction of combined slip characteristics based on the test datas under pure slip condition,but the prediction range and accuracy of the model needed to be improved.The tire models with prediction ability could reduce the amount of test,and had application prospects in improving the product development efficiency and cost control.Research on tire models that had high-precision,high calculation efficiency,low cost,short development cycle,and could reflect changes in design parameters was an important direction of model development.
