Parameterized Design And Optimization Of Boom Of Ship Crane Based On APDL

Ship cranes have many advantages such as flexible and adaptable. It is shown that ship cranes are playing more and more important roles in the world. This also requires ship cranes to having stricter technical capability. On the other side, the broad application of computers stimulates the appearance of many advanced design methods over the single subject, which promotes the design and manufacture standard of ship cranes. As we all know, the intense international market competition relies on the technical competition closely. This will spur crane's technical capability up to a new development step. As computer technology continues to develop, parametric modeling and finite element analysis technology more and more applications to the modem mechanical design process.This paper has a parametric analysis and optimal design on a boom structure of ship crane, to build a crane structure's parameterized FEM model using ANSYS internal command-APDL and parameterized method, using secondary development technology of ANSYS to complete parametric analysis, on this basis to complete optimal design of boom. It is conveniently and quickly to modify and recalculate the model in FEM analyzing. This article merges the design, model building, analyzing, optimizing into an organic whole, which possesses an important meaning to raise the design standard and efficiency of the boom.Mechanics analysis and parameter optimization on the boom framework have been done by using ANSYS10.0, the large general finite element analysis software. The method of its secondary development technology has been described. A design approach based on ANSYS for finite element analysis and parameter optimization of the boom framework has been given and its implementation procedure has been shown by concrete examples. On the basis of the above study, a program module for design and analysis of the boom framework which based on APDL is developed by the author. This program module includes several parts such as models constitution, finite element analysis and parameter optimization. The results shown in the thesis not only provide a scientific and rational design methods, but also benefit for shortening design period and improving work efficiency.The study in this thesis is a successful practice of finite element analysis and parameter optimization on finite framework of boom of ship crane. Meantime, the secondary development technology of ANSYS and its realization course shown in the thesis could be a successful reference for the others to analyze and resolve actual engineering problems.
