基于开关半主动的潜艇推进轴系纵向隔振控制研究
Study on longitudinal vibration isolation control of submarine propulsion shaft system based on switching semiactive
摘要
Abstract
Aiming at the longitudinal vibration problem of propulsion shaft system caused by submarine sailing process,the longitudinal vibration isolation control of shaft system under switching semi-active control is carried out.A switching semi-active vibration isolator is designed and combined with the longitudinal vibration of the propulsion shaft system.Based on the canopy damping control strategy,the semi-active switching control algorithm is proposed to study the effect of the longitudinal vibration isolation control of the propulsion shaft system under different static thrust loading and different control states.The results show that,at the same static thrust,the switching semi-active vibration isolator has obvious suppression effect on the longitudinal vibration of the propulsion shaft system,and the base speed frequency response of the propulsion shaft system in the low-frequency band is reduced by more than 50%,which effectively suppresses the low-frequency resonance,and the vibration in the middle and high-frequen-cy bands also has a good effect of vibration control;in the case of different static thrusts,the lower the static thrust is,the better the effect of vibration isolation of the switching semi-active vibration isolator is.The study shows that the switching semi-active control can effectively reduce the longitudinal vibration of the propulsion shaft system,and obtain a better control effect in the full frequency band.关键词
