说明：  矢量控制是目前交流电机的先进控制方式，一般将含有矢量变换的交流电机控制都称 之为矢量控制，实际上只有建立在等效直流机模型上，并按转子磁场准确定向的控制，电机才能获得最优的动态性能。 矢量控制的基本思路是以产生相同的旋转磁动势为准则，将异步电机在静止三相坐标系上的定子交流电流通过坐标变换等效成同步旋转坐标系上的直流电流，分别加以控制，以达到直流电机的控制效果。(Vector control is an advanced control method of AC motor at present. Generally, vector control is called vector control. In fact, only based on the equivalent DC motor model and accurately oriented control according to the rotor magnetic field, can the motor obtain the optimal dynamic performance. The basic idea of vector control is to generate the same rotating magnetomotive force as the criterion. The stator AC current of asynchronous motor in the static three-phase coordinate system is converted into DC current in the synchronous rotating coordinate system by coordinate transformation, and then controlled separately to achieve the control effect of DC motor.)

本文建立了独立悬架汽车整车七自由度动力学模型，推导了振动微分方程，运用数值仿真的手段研究了汽车悬架阻尼系数、刚度等设计参数对汽车振动特性的影响规律。结果表明，在共振区域附近，相对较大的刚度，会导致汽车的舒适性下降，但在共振区以外的高频区，刚度对汽车振动幅值的影响并不大；后桥悬挂阻尼对汽车振动幅值的影响较前桥强烈，适当增大后桥悬挂的阻尼有利于振动幅值的降低(This paper established an independent suspension vehicle dynamic model of seven degree of freedom, the vibration differential equation is derived, using the numerical simulation method of vehicle suspension damping coefficient, influence of design parameters on vehicle vibration characteristics of stiffness. The results show that in the resonance region, a relatively large stiffness, will lead to the comfort of the car down, but in the resonance region outside the high frequency region, the effect of stiffness of the vehicle vibration amplitude is small; the effect of damping on automobile suspension vibration amplitude is strongly increasing the rear axle axle, suspension damping to reduce the vibration amplitude)
