Overall Design and Analysis of Vibration-Isolated Foundation for Forging Hammers

Xu Rongguang; Zhang Zhongxian; Tang Jiaxing(Asso. Prof.; Dept. of Civil Eng., HUST, Wuhan 430074, China.)  
The structure of the vibration-isolation system for a forging hammer, the main components, and the system behavior are briefly described. The mechanism of the vibration-isolated foundation is discussed. The selection of the parameters of the components and the development of the mechanical model are investigated. The steel dish-springs are used as the vibration-isolated member, and the steel-wire rope damper as the main damping component, and a buck-pressure type amplitude limited is used to control the resilience of anvil block. As contrasted to the rubber-make vibration-isolation member, the system developed is characterized with non-aging and long life expectancy, and it is found that the acceleration of the hammer foundation is reduced by 94%, and the foundation displacement is reduced by 87% after the rubber foundation is replaced by dish-spring one.
