Abstract

In the study of telescopic boom dynamics, section deformation is often neglected. However, it has an important impact on the performance of the telescopic boom. In this paper, a one-dimensional dynamic model of hexagonal telescopic boom structure considering the cross-section deformation is established. The model considers the displacement field through the linearly superimposing of 29 basis deformation modes, which stem from the discretization of the cross-section into 8 segments. The corresponding deformation function approximated with Hermite interpolation. Involved with the principle of Hamilton, the governing equation is deduced, which is then interpolated with quadratic Lagrange for the finite element implementation. The accuracy of the new model in capturing dynamic characteristics of telescopic boom is proved by a special example.
