轮胎操稳非稳态特性建模的理论与方法

Modeling for Tire Handling Transient Properties

为合理表达非稳态工况下轮胎力学特性,基于当前工作点轮胎物理模型描述,提出了一种全新的轮胎非稳态特性建模方法,给出了模型求解流程,并展示了TMPT部分非稳态工况仿真结果。所提出的模型具有适用于任意非稳态工况、非恒定松弛长度、高速与低速特性统一表达的特点。

For the purpose of modeling tire nonsteady state properties, a new tire transient model is presented based on the establishing of tire physical model on working point. The model calculation procedure is given and some simulation results of TMPT are illustrated. By reason of adopting the nonconstant relaxation length and one set of equations for tire high and low speed properties, the new transient model is applicable to comprehensive nonsteady state simulations.
