汽车轮胎与整车匹配所构成的集成系统的动力学性能是影响汽车行驶性能的主要因素。为了提高汽车轮胎与整车驱动性能匹配的合理性,采用轮胎三维有限元分析方法分析了汽车轮胎驱动性能,建立了汽车轮胎驱动特性模型,并与传统刷子模型进行了对比分析,在此基础上研究了与轮胎匹配的整车驱动性能特性。针对某越野车型建立了其加速过程的数学模型,在MATLAB/Simulink仿真环境下进行了整车驱动性能动态仿真,并与实验结果进行对比分析,结果表明:利用新的轮胎模型进行整车驱动性能仿真分析能够准确地反映整车驱动特性。
The dynamic performance of the integrated system formed by matching the car tire with the whole vehicle is the main factor that affects the driving performance of the car. In order to improve the rationality of the match between the driving performance of the automobile tire and the whole vehicle, the driving performance of the automobile tire is analyzed by the three-dimensional finite element analysis method of the tire, the driving characteristic model of the automobile tire is established and compared with the traditional brush model. On this basis The driving performance characteristics of the vehicle matched with the tire are studied. A mathematical model of acceleration process is established for a certain off-road vehicle. Dynamic simulation of vehicle driving performance under MATLAB / Simulink simulation is carried out and compared with the experimental results. The results show that using the new tire model for vehicle driving performance Simulation analysis can accurately reflect the vehicle driving characteristics.
