Abstract

In this paper, addressed to the problems existed in the squeeze film damper (SFD) based on the dynamic pressure bearing in the rotational machinery, a new type of the hybrid squeeze film damper (HSFD) with piezoelectric crystal electro-hydraulic active control is proposed. It is composed of dynamic pressure bearing and static pressure bearing. The effectiveness of HSFD is analyzed theoretically, and the simulation of the chaos dynamics characteristics is carried out. The results obviously show that the HSFD not only overcomes the bi stable problem, but also restrains the shock in the rotor supporting system.
