Abstract: A traditional lumpedmass model for the boom shipmounted crane is established in this paper. The nonlinear dynamic equation is presented using the EulerLagrange method. Then the nonlinear dynamic behavior of the cable is analyzed numerically, and the impact of some key parameters on the cargo pendulum is studied. Results of this study are of significance for the operation of shipmounted cranes.

Key words: vibration and wave, vibration analysis, boom shipmounted crane, EulerLagrange method, numerical analysis
