Abstract

In accordance with the problem existed in rotating machinery using traditional squeeze film damper combined with dynamic pressure bearing, the electrohydraulic squeeze film damper (HSFD) was proposed, which is hybrid oil film bearing composed of dynamic and static pressure with piezoelectric crystal-electrohydraulic active control. To solve the pressure distribution of the HSFD, the solution method applied to solve the Reynolds equation with hybrid action of static and dynamic pressure was proposed. Based on this, the theoretical analysis for rotor system with the HSFD was conducted, which lay the foundation to realize active control.
