【摘要】：电控适时四驱系统在城市型SUV上得到了越来越广泛的应用。作为许多适时四驱系统的关键执行部件,轴间扭矩管理器的动力学特性对整车性能有着重要影响。针对博格华纳Nextrac轴间管理器进行动力学建模研究。利用有限元软件对电磁执行机构的点此特性进行了分析,设计了不同状态下扭矩管理器的切换规律,制定了各状态下扭矩管理器的扭矩传递模型。通过搭建simulink模型和Carsim-Simulink联合仿真平台进行仿真验证。并将仿真结果与实际数据比较,结果验证了模型的有效性。
[Abstract]:The electrically controlled timely four-drive system is more and more widely used in urban SUV. It is the key component of many timely four-drive systems. The dynamic characteristics of the shaft torque manager have an important effect on the performance of the whole vehicle. The dynamic modeling of the Borg Warner Nextrac intershaft manager is studied. The point of the electromagnetic actuator is analyzed by using the finite element software. The characteristics are analyzed. The switching rule of torque manager in different states is designed. The torque transfer model of torque manager in each state is established, and the simulation results are verified by setting up simulink model and Carsim-Simulink simulation platform. Actual data comparison. The results show that the model is effective.
