车辆系统动力学主动悬架仿真,可以直观的看到悬架限位行程-Vehicle system dynamics simulation of active suspension

七自由度仿真模型，带有驾驶员模型，传动系统模型。(Seven-degree-of-freedom simulation model with driver model and driveline model.)

建立了车辆—轨道偶合动力学模型，使用Romberg观测器观测了轮对位移、轮对速度、车体速度等系统状态量。(The vehicle-track coupling dynamic model is established, and the wheel-set displacement, wheelset velocity, vehicle body velocity is observed by using Romberg observer.)
