Research On Crane Structure Optimization Based On SiPESC Platform

As one of the main construction machinery,the crane can be commonly used in the construction of industrial and civil buildings.The crane boom is one of the essential structural component for cranes to realize heavy lifting and rotation,the performance of crane depends on rational structure of the boom,so it is especially necessary to optimize the design of the boom structure.This article aims at the optimization design for various types of the crane boom structures,applies multiple optimization methods of the SiPESC.OPT,uses the APDL design language for parametric modeling,and invokes the ANSYS software to implement the finite element analysis process,optimizes the various types of boom structure to realize the lightweight structure under the safety regulations.In view of the Crane structure optimization,the paper uses the Python language to write scripts to achieve joint optimization based on SiPESC.OPT optimization analysis and ANSYS limited calculation.The paper studies the cross-sectional dimensions of the crawler crane boom,uses the SiPESC.OPT and the OPTISTRUCT optimization solver for analysis,and compares the optimization calculation results to verify the feasibility and accuracy of the SiPESC.OPT.At the same time,the paper verifies the diversity of the SiPESC.OPT,uses the different optimization algorithms of the SiPESC.OPT for the same optimization problem of the boom tower crane.Under various working conditions with different working ranges,the SiPESC and the APDL are used to lighten the large crawler crane with a boom length of 96 m,on the premise that the structural load-bearing capacity remains unchanged,improve the safety and rationality of the structure,and save costs.
