英文摘要：

In order to promote the development and application of the Blisk linear friction welding technology,the vibration rules between piston and fixtures of welding machine were analyzed based on vibration theory.The model of single degree of freedom forced vibration was set up to find the equivalent value of vibration parameters of the system.The results shown clearly the vibration laws of system and were useful for designing the welding machine vibration system.
