Embodiment Construction

[0024] In the following, with reference to the accompanying drawings, a crawler crane boom is taken as an example to further illustrate the present invention.

[0025] figure 1 Shows the mechanism relationship diagram of the truss boom system class module. The boom class is the top class, which contains all the contents of the model, including the component class; the component class can further include the materials, sections, nodes and elements of the components, The material type, section type, element type, and node type are the bottom type and constitute other parts. Specifically, the material category contains the characteristic parameters of the material used in the boom structure, such as material name, density, elastic modulus, etc.; the section steel section contains the section parameters of the section steel used in the boom, such as the basic parameters of the section name, section size, etc. , It also contains methods that can calculate parameters such as cross-sect...

Abstract

The invention discloses an object-oriented computer modeling method based on a crane boom. The object-oriented computer modeling method includes the following steps: firstly, partitioning unit modules off to acquire size, material, section and structural feature, encapsulating by an object-oriented method and creating various classes; secondly, acquiring modeling data of a crane boom structure and creating a material object, a structural steel section object and a component object; thirdly, acquiring crane-boom-type data, forming a crane boom system and storing parameters in a database; fourthly, entering the crane-boom-type data into a finite element module to create a finite element model of the crane boom system for analyzing, calculating and sending out analysis results; fifthly, extracting the data of the results according to the requirements of users and sending the data of the results, such as lists, graphs and animations to analysis report files; sixthly, finishing and releasing space. The object-oriented computer modeling method has the advantages of being strong in object-oriented modeling capacity, complete in data check function, and good in compatibility and portability.

Description

Technical field [0001] The invention belongs to the field of cranes and relates to an object-oriented crane jib computer modeling method. Background technique [0002] The rapid development of the domestic economy and the urgent need for infrastructure construction have promoted the rapid development of my country's crane technology. The boom structure is used in tower cranes, crawler cranes, wheeled cranes and other boom cranes due to its mobility, flexibility, and lightness. It is widely used in industrial and mining enterprises, construction sites, ports, oil fields, warehouses, freight yards, etc. Lifting operations and hoisting work such as lifting and installation in stations and cities. [0003] Since the 1950s, the crane manufacturing industry in my country has experienced crane design from the introduction of the former Soviet Union, imitating European and American products to independent innovation and development. Although the tonnage of our country's jib crane product...
