Optimization Design of Arm Frame of Folding Arm Type Tower Crane Based on ANSYS

Abstract

Aiming at the problem of the light weight of the arm frame structure of some folding arm type tower crane at present. The folding arm type tower crane jib is analyzed based on the APDL language, including parametric modeling module and optimization design module, Finite element analysis is carried out on the condition of the most dangerous position at the end of the arm frame. Under the condition of the strength, rigidity and stability of the boom, the optimization function of ANSYS is used to reduce the weight of the boom. Through analysis, the optimization results are compared with the original design scheme and the weight of the arm is reduced by 14.89%. The optimization effect is good, which greatly improves the quality and efficiency of the design. The reference is provided for the design of the metal structure or similar structure of the arm frame of the folding arm type tower crane.
