Abstract

The invention relates to the technical field of fast loading methods for finite element analysis loads, in particular to a fast loading method for structural finite elements, which comprises the following steps of: selecting original structural loads, and classifying the original loads into distributed surface loads, concentrated forces and discrete point forces. According to the structural finite element rapid loading method, the external load is rapidly mapped to the coordinate positions corresponding to the nodes and the units of the finite element model, rapid loading from the structural load to the finite element model can be achieved, a formatted loading card is generated, and the method is rapid, efficient and convenient to reuse. According to the method, the finite element loading efficiency can be greatly improved, and the pretreatment work is simplified.

Description

technical field

[0001] The invention relates to the technical field of fast loading methods for finite element analysis loads, in particular to a fast loading method for structural finite elements. Background technique

[0002] For complex finite element models, the application of finite element loads under multiple working conditions is a complicated and highly arbitrary task, and the loading method of finite element models, the distribution and value of input loads, have great influence on the accuracy of finite element calculation results. Responsibility is decisive, which requires an efficient, accurate and simple loading scheme.

[0003] The traditional load calculation does not have the assistance of 3D display in the early stage. The first common method is to distribute the original load to the nearest station node, and then distribute the station node to the finite element nodes around the station; the second is to distribute the original load It is allocated to the...
