| Abstract: | The paper points out that in the structure lightweight design of the tower crane, adopting high strength structure steel instead of common Q235 carbon structural steel can release the tower crane weight, gets dynamic characteristic analysis on the QTZ40 tower crane based on the finite element program ANSYS, establishes finite dement analysis model of the tower crane, calculates and discusses the natural fre-quency and vibration modal of the former six modal of the tower crane, so as to perfect the dynamic design of the tower crane. |
