摘要： 为提高车辆平顺性及驾乘体验，基于天棚阻尼控制策略，利用 MATLAB/Simulink 搭建 了一套垂向减振器半主动悬架控制模型，并在扭曲路工况进行车辆动力学仿真分析，实现了 该策略在软件层面的有效性验证；将上述模型进行通道匹配，并移植烧录至硬件 dSPACE MicroAutoBox III 中进行实车特征路的验证工作。主、客观相关数据表明，天棚阻尼控制下的 半主动悬架，能使车辆主驾驶位座椅加速度均方根值明显减小，车辆的前后轴冲击、振动收 敛、车身姿态等均有明显改善，验证了天棚阻尼控制策略在工程中的有效性。

Abstract: In order to improve the ride and driving experience of the vehicle, based on the skyhook damping control strategy, a set of semi-active suspension control model of vertical damper is built using MATLAB/Simulink, and the vehicle dynamics simulation analysis is carried out under the twisted road conditions, and the effectiveness of the strategy is verified at the software level. The above model is matched with the channel, and transplanted and burned to the hardware dSPACE MicroAutoBox III for the verification of the real vehicle characteristic path. The subjective and objective data show that the root mean square value of the acceleration of the seat in the driver's seat of the vehicle under the control of the canopy damping is significantly reduced, and the front and rear axle impact, vibration convergence, body attitude, etc. of the vehicle are significantly improved, which verifies the effectiveness of the skyhook damping control strategy in the project.
