- Abstract:
-
The elastic second-order force performance of the one-layer and two-layer attachment of the attached tower crane is discussed. Taking KZQ2000Z tower crane as the research object, the corresponding simplified calculation model is proposed, and the second-order effect analysis of the simplified model is carried out and compared with the results of the finite element software analysis and calculation, and the maximum difference of the calculation results is 3.9%.The analysis results show that the proposed simplified model can reflect the elastic second-order characteristics of the actual tower crane, and the second-order force characteristics of the tower crane are obvious when the lifting weight is large.
