Abstract: In order to make the FV-1200 vertical shaft impact crusher run smoothly under the work⁃ ing condition of high speed，aiming at the working condition of the equipment and its vibration influence on the crushing cavity and motor seat of the main engine due to the impact force and centrifugal force of the material under the running state，through the research on the working principle and structural form of the FV-1200 vertical shaft impact crusher，the design of the vibration reduction system and the auxiliary analy⁃ sis of the three-dimensional software are carried out，and the analysis results of the compression deforma⁃ tion of the vibration reduction pad are obtained. Finally，the analysis results are compared with the industri⁃ al test results，and the validity of the analysis results is obtained. It shows that the vibration reduction sys⁃ tem meets the design requirements，which can provide reference for the subsequent optimization design and the smooth operation of the equipment.

Key words: FV-1200 vertical shaft impact crusher, vibration reduction system, compression amount
