摘　　要：文章通过对某车辆转向系统的台架测试,提取了该转向系统的刚度、助力和摩擦性能参数,并将其建立为相应的模型输入到所搭建的转向系统模型中。随后,对定半径稳态回转、转向盘角阶跃和中心区转向这三个典型工况进行了仿真与试验对比研究。研究结果表明,经过精确建模的仿真模型对各个评价指标的预测较为准确,且对转向盘力矩的测试结果也具有较高的预测精度。文章还通过插件将ADAMS/Car模型导出为VI-CarRealTime模型,并详细阐述了VI-CarRealTime齿轮齿条模型的建立方法。通过对齿轮齿条模型的搭建,进一步验证了VI-CarRealTime与ADAMS/Car模型的对标精度。该研究对转向系统的建模与仿真方法进行了深入探讨,并在实验验证中取得了良好的预测精度。这对于提高车辆转向系统设计的准确性和效率具有重要意义,为相关领域的研究和实践提供了有价值的参考和借鉴。In this paper,the stiffness,power and friction parameters of a vehicle steering system are extracted by bench test,and the parameters are built into the corresponding model and input into the steering system model.Then,three typical operating conditions of steady turning with fixed radius,steering wheel angle step and central steering are studied by simulation and experiment.The results show that the simulation model with accurate modeling can predict each evaluation index more accurately,and also has higher prediction accuracy for the test results of steering wheel torque.The ADAMS/Car model is exported to VI-CarRealTime model by add-on,and the establishment method of the VI-CarRealTime rack and pinion model is described in detail.The calibration accuracy of VI-CarRealTime and ADAMS/Car model is further verified by building a rack and pinion model.In this study,the modeling and simulation methods of the steering system are deeply discussed,and good prediction accuracy is obtained in the experimental verification.It is of great significance to improve the accuracy and efficiency of vehicle steering system design,and provides a valuable reference for research and practice in related fields.
