| Abstract: | Strength and vibration are important parameters in the design of tower crane.Ensemble modeling of tower crane is carried out in this paper through finite element method.Based on this model,strength character and vibration character are analyzed.Position of limit strength also vibration frequency and shape are brought forward,which offers a foundation for studies on other responses to dynamics of tower crane. |
