Paper Abstract
An engine is one of the most dominant noise and vibration sources in vehicle systems. Therefore, in order to resolve
noise and vibration problems due to engine, various types of engine mounts have been proposed. This work presents a
new type of active engine mount system featuring a magneto-rheological (MR) fluid and a piezostack actuator. As a first
step, six degrees-of freedom dynamic model of an in-line four-cylinder engine which has three points mounting system
is derived by considering the dynamic behaviors of MR mount and piezostack mount. In the configuration of engine
mount system, two MR mounts are installed for vibration control of roll mode motion whose energy is very high in low
frequency range, while one piezostack mount is installed for vibration control of bounce and pitch mode motion whose
energy is relatively high in high frequency range. As a second step, linear quadratic regulator (LQR) controller is
synthesized to actively control the imposed vibration. In order to demonstrate the effectiveness of the proposed active
engine mount, vibration control performances are evaluated under various engine operating speeds (wide frequency
range).
