从提高汽车的乘坐舒适性出发，设计了以发动机液力悬置为基础，带有压电作动器的主动式发动机悬置，并建立了它的力学模型，应用最小均方法（LMS）对发动机的振动进行了主动控制的仿真分析。结果表明，液力压电悬置可以有效控制发动机的振动向车身地板的传递，同时也证明了LMS控制方法适合于发动机振动的主动控制。

Study of LMS control method on active engine mount is carried out for ride quality improvement. Take an active engine mount which is based and developed from a hydraulic mount with decoupled disc-membrane as a module, the characteristic of vibration isolation of active engine mount is simulated and analyzed. The results indicated that active engine mount could reduce the vertical vibration effectively with LMS Control method.
