摘要
为了提高仿真模型的计算效率,基于环模型理论系统研究了轮胎二维有限元模型的建模技术、参数确定方法和轮胎包容特性分析技术。从试验与仿真结果对比分析可知,利用有限元方法基于轮胎REF模型建模,在对轮胎胎侧弹性进行非线性模型修正后,得到的轮胎低速滚动仿真结果与试验结果基本吻合,验证了轮胎模型的有效性,同时为车辆-地面系统虚拟试验提供了一种实时高精度的轮胎面内特性仿真建模方法。
To improve calculating efficiency of simulation model,tire 2D FE model modeling technique,parameter determination method and tire enveloping characteristics analysis technique are studied based on circle model theory system.It is concluded from comparison between test and simulation results that use FE method and model based on tire FEF model,after revising nonlinearly the lateral elasticity of tire,the simulation result of tire low speed rolling coincides with test results,thus proving validity of tire model,meanwhile a real-time high precision tire characteristics simulation model method is provided for the virtual test of the vehicle-road system.
