- In order to analyze accurately the deformation of the telescopic boom in the case of large deformation, an initial deflection curve can be get according to the nonlinear bending differential equation and calculation method. The retraction amount in initial axial direction of the boom and the second-order bending moment can be get after counting process with the initial deflection curve. Then these data can be used to amend the bending moment in the nonlinear bending differential equation and so a more accurate deflection curve can be get. The deflection curves of a typical telescopic boom were calculated and the results were compared with the results obtained by the approximate calculation method. The results show that the calculation method proposed in this paper can obtain the deflection curve of the telescopic boom accurately under large deformation condition. The results obtained by using the traditional approximation of the calculation method are too large.
