Stability analysis of the crawler crane jib

  • The influential factors were studied on the stability of crane jib for the increase of strength,at the same time stiffness and buckling resistance decrease in view of a large number of adoption of high strength steel in crawler crane.The jib model was established based on the finite element software ANSYS,the static state and the eigenvalue buckling were analyzed and the nonlinear buckling analysis was carried out on the jib on the basis of eigenvalue buckling mode shape as initial defects.It was found that the wind load and horizontal inertial force influence on the stability of the boom was relatively small,while the deflection force was the main factor that causes the unstability of the jib.
