Title: $Study on Coupled Vibration Characteristics of Inclined Isolation System
Abstract: To solve vibration isolation problems in powerplant engineering, the dynamic model of an inclined isolation system based on a flexible foundation subjected to combined excitations is proposed. A set of matrix formulations related to dynamic parameters of the vibration isolation system is derived, and the expression of power flow transmission function of the system is presented. Transverse-and-roll coupled vibration characteristics of the system are studied deeply. Effects of the vibration isolation system under the decoupling conditions are explored. It is found that the system can be decoupled and the system's vibration transfer energy can be reduced significantly when the structure parameters of the mounts are reasonably selected.
