Optimization Design Of Lifting Mechanism Of Bridge Crane Based On Object-oriented Technology

Crane is working in power plants,workshops,shipyards,mining and other places of lifting equipments.With the increasing demand for cranes in all walks of life,China’s crane industry is developing rapidly and fiercely competitive,and the crane design is developing rapidly towards customization,lightweight and larges cale.In view of the low efficiency of the traditional design process of the crane,in order to improve the design efficiency of the crane,it is necessary to optimize the design process of the whole crane.In this paper,the problem of inefficiency of the traditional design method of bridge crane hoisting mechanism is optimized,and the design flow of hoisting mechanism is specially optimized.In this paper,bridge crane hoisting mechanism is taken as the research object.Based on the object-oriented design idea,database technology and the parameterized technology,this paper establishes an object-oriented optimal design and calculation system for the bridge crane hoisting mechanism system,fully optimized traditional hoisting mechanism design process.Finally,the Ansys Workbench software is used for the finite element modeling and optimization of the important components.The research content of this paper:(1)The composition and principle of hoisting mechanism and the design and calculation method of hoisting mechanism are analyzed.(2)Using the idea of object-oriented,this paper abstract the hoisting mechanism object,and calculate and analyze the hoisting mechanism through the hoisting mechanism design and calculation program.The database stores the parts of the hoisting mechanism kinds of data.(3)The 3D software Solid Works is used as the development platform,the parametric design of the hoisting mechanism is implemented by using VB,and finally the Ansys Workbench is used to carry out the finite element analysis and optimization of the drum.The ideas of object-oriented technology and parametric design computation are combined to construct this optimization design system of hoisting mechanism based on object-oriented technology.The corresponding technology are fully used to design and compute partial mechanism of hoisting mechanism.This system makes the deviser’s design convenient and design period is shortened,an in the mean time work efficiency is improved.
