Embodiment Construction

[0024] Below in conjunction with accompanying drawing, take the boom of crawler crane as example, the present invention will be further described.

[0025] figure 1 Shows the institutional relationship diagram of the truss boom system class module, the boom class is the top-level class, including all the contents of the model, including the component class; the component class can further include the materials, sections, nodes and units that make up the component, Material class, steel section class, unit class and node class are the bottom classes, which form other parts. Specifically, the material category includes the characteristic parameters of the materials used in the boom structure, such as material name, density, elastic modulus, etc.; the profile steel section category includes the section parameters of the profile steel used in the boom frame, such as section name, section size and other basic parameters , and also contains methods to calculate the cross-sectional ...

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 computer modeling method for a crane jib. Background technique [0002] The rapid development of the domestic economy and the urgent need for infrastructure construction have promoted the rapid development of crane technology in our country. The jib structure is widely used in tower cranes, crawler cranes, wheeled cranes and other jib cranes due to its maneuverability, flexibility, and portability. It is widely used in industrial and mining enterprises, construction sites, port terminals, oil fields, warehouses, freight yards, Lifting operations and hoisting work such as lifting installations in stations and cities. [0003] Since the 1950s in my country's crane manufacturing industry, the design of cranes has gone through the stages of importing from the former Soviet Union, imitating European and American products, and developing independently. Although the tonnage of m...
