基于dSPACE的液压式主动稳定杆实验平台设计

为研究液压式主动稳定杆对汽车在高速转向时侧倾稳定性的影响,设计并实现了液压式主动稳定杆硬件在环(hardware-in-the-loop,HIL)仿真实验平台。以单/双轴通用稳定杆实验台架为基础,使用MC9S12DG128单片机为核心设计控制器,利用dSPACE实时仿真系统运行整车动力学模型,研究典型转向工况和不同类型路面激励情况下的液压式主动稳定杆对车辆侧倾稳定性的改善情况。实验结果表明,该实验平台能够很好地模拟实验环境,为主动稳定杆系统的开发提供了有力的支持。

Design of hydraulic active stabilizer bar test platform based on dSPACE

For the study of the influence of hydraulic active stabilizer bar to vehicle lateral stability under high speed steering maneuver, the hydraulic active stabilizer bar HIL test platform is implemented. The HIL test platform is designed with single/double axles universal test bench to experiment on single or double axles active stabilizer bar, using MC9S12DG128 microcontroller as the core controller and running vehicle dynamics model in the dSPACE. This HIL platform is used to study the effect of the hydraulic active stabilizer bar on the vehicle roll stability under different types of the road and typical steering maneuvers. The experiment results illustrate that the hydraulic active stabilizer bar HIL test platform can simulate the experiment environment and provide a powerful support for the development of active stabilizer bar system.
