Abstract

In order to optimize structure parameters of lifting drum, the buckling stability of drum on crane is analyzed infinite element method with Euler distribution force which is more appropriate to the realistic load state. The results of finite element analysis are compared with the computing results of traditional simplified method. The research provides a new idea for the stability optimization design on lifting drum as cylindrical shell structure with complex inner rib plate.

Highlights

The drum, as the most important force component of crane, the design of stability of it is directly related to the normal work of crane
Many important works in this field have been studied, Yixiao Qin represented a coupling between the optimum method of advance and retreat and the finite element analysis for the design on large hoist drums of crane [1], the finite element analysis of crane’s drum was studied [2], the buckling stability analysis of 1600t crane’s drum is analyzed based on ANSYS [3]
Many stability analysis consider the drum as an ideal model of cylinder shell in uniform compression [4, 5, 6]

Summary

Introduction

The drum, as the most important force component of crane, the design of stability of it is directly related to the normal work of crane. Many important works in this field have been studied, Yixiao Qin represented a coupling between the optimum method of advance and retreat and the finite element analysis for the design on large hoist drums of crane [1], the finite element analysis of crane’s drum was studied [2], the buckling stability analysis of 1600t crane’s drum is analyzed based on ANSYS [3]. The model of drum is set up based on the feature of structure and stress which depend on the force distribution and equilibrium relationship. The relationship between structural distortion, the variation of stresses and wall thickness of crane are studied, the results between FEM and conventional design method based on experience design and static design are compared. The heavy and structure parameters of crane’s drum are optimized for the model is imitated properly
