摘　　要：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,应用最小均方算法(LM S)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。Study 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 predicted results indicated that the engine vertical vibration can be reduced effectively with hydraulic-piezoelectric mount.
