“…High strength steel WELDOX 960MPa was applied in the Jib structure and copper was applied in the slider structure. For the accuracy of the telescopic cylinder supporting effect, establish the movement restriction between cylinder and the Jib by using connector [4]. Use surface to surface contact between the Jib and sliders, define the friction formulation by means of Penalty, friction ratio µ=0.1; meanwhile use Lagrange multiplier method to strengthen the contact boundary restriction.…”

The existence of boundary condition and friction are difficult to predict which makes the sliders contact situation extremely complex. The actual response of the contact region becomes a tough research by using traditional method. Taking the cylinder supporting function into account, the polygonal and similar-oval Jib models are established. Research of the stress distribution and the stress concentration phenomenon is analyzed. The results indicate that stress distribution of the sliders of the similar-oval Jib is more uniform in comparison with the polygonal Jib that it can ameliorate the stress state of the contact region and enhance the partial stability of the Jib.
