ER마운트 제어에 의한 원통셸의 진동소음 해석

Noise and Vibration Analysis of a cylindrical shell by controlling ER mount

  • 발행 : 2002.11.01

초록

ER mount is often used instead of rubber mount in cylindrical shell to improve the vibration and noise performanec. The noise radiated by cylindrical shell will be reduced by reducing the force transmitted to the cylindrical shell through ER mount. In this paper, LQ control theory is used to reduce the transmitted force to the cylindrical shell. The finite element method of cylindrical shell is formulated by NASTRAN and its vibrating shape is calculated in frequency domain. (omitted)
