摘要
针对当前车辆动力学模拟与动态控制研究中所采用的经验轮胎模型需要大量实验数据的情况,探讨了利用理论轮胎模型来进行车辆动力学建模与仿真的实现方法,以改善轮胎经验模型对实验数据过于依赖的不足。通过研究,利用MATLAB/Simulink软件实现了Gim理论轮胎模型的模块化建模和动力学仿真分析。仿真结果和实验数据的对比表明:Gim理论轮胎模型的精度高,能准确预测轮胎的力学特性;所建立的Simulink轮胎子模块通用性强,所需参数少,运算快,为车辆动力学的实时仿真提供了很大方便。
Because the tire empirical model often requires a large number of experimental data in the research of vehicle dynamics simulation, it explores the implementation of the physical tire model to improve the lack of tire empirical model over - reliance on experimental data. Based on research an Matlab/Simulinl〈, it establishes a tire modular of the GIM model and executes a simulation. The comparison of simulation results and experimental data show that Gim tire model has high precision and the advantages of good universality, is rapid calculation, can accurately predict the tires mechanical properties, require fewer parameter, so this tire modular provides great convenience for real -time simulation of vehicle dynamics.
