Short summary
A super element of the telescopic boom for an all-terrain crane is proposed, and its geometric nonlinear calculation is realized by the co-rotational (CR) formulation. Considering the cable force, the nonlinear equilibrium equations of the system are established, which are transformed into differential equations, and the load displacement curves of the nodes are obtained. Through the slope ratio of the load displacement curve, the judgment criterion of the instability load is established.
