Study on structural instability of large crawler crane boom structure

摘要：

Taking a certain large crawler crane boom as research object, the local buckling critical load is calculated by finite element analysis, and a fullrange analysis for the boom structure is conducted. The analysis method of boom structure instability propagation process is established, and the true load response of actual structure is reconstructed. The results show that the dynamic effect is obvious after the occurrence of local instability accompanied with dynamic hopping. The research results of this paper have certain reference value to make measures for preventing the instability propagation, and also have guiding significance for the large boom structure design.
