A Study on Active Engine Vibration Control by Applying Hydraulic-Piezoelectric Mount

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.
