Embodiment Construction

[0026] The present invention will be further described below in conjunction with accompanying drawing.

[0027] see figure 1 , the figure shows a kind of crane universal girder parametric computer modeling method of the present invention, comprises the following steps:

[0028] Step S1, initialize various data structures, that is, initialize various data structures when the program starts, and then enter step S2 and step S3 respectively;

[0029] Step S2, select the main girder type and input parametric modeling data, that is, select each parametric structure of the main girder and input various main girder parameter values, select the overall structural size, end size, rib plate and other dimensions of the main girder , material properties and / or grid size, and then enter step S3;

[0030] Step S3, obtain parametric modeling data, determine the main girder type and end wheel support form according to the input parametric modeling data and various data structures after initi...

Abstract

The invention discloses a parameterized computer modeling method for universal main girders of cranes, which comprises the following steps of: initializing various data structures; selecting the type of a main girder, and inputting parameterized modeling data; acquiring the parameterized modeling data; according to the acquired data, filling the various data structures; controlling a ANSYS to carry out a plurality of operations by using a packaged APDL (ANSYS parametric design language) command; carrying out post-processing analysis; and completing the modeling and releasing the space. The parameterized computer modeling method for universal main girders of cranes disclosed by the invention is a convenient, easy-to-use and reliable parameterized computer modeling method for main girders, which is re-developed on the basis of the current computer analysis system.

Description

technical field [0001] The invention relates to a computer modeling method, in particular to a parametric computer modeling method for a universal main girder of a crane. Background technique [0002] With the rapid development of modern science and technology, the expansion of industrial production scale and the improvement of automation, cranes are more and more widely used in the modern production process, and their role is becoming more and more important. The requirements for cranes are also getting higher and higher. The characteristics and development trend of modern cranes are embodied in the following aspects: large-scale key products; modularization of series products; miniaturization and light weight of general products; automatic product performance; and flexible product manufacturing. [0003] my country's crane manufacturing industry started in the 1950s. At this stage, most crane designs were imported from the former Soviet Union. Therefore, the early steel s...
