Problems solved by technology

The original trailer operation can no longer meet the needs of the current port. Therefore, the heavy-duty AGV came into being. It is a handling equipment for container terminals equipped with automatic guidance systems. Compared with the handling equipment of traditional container terminals, It has the advantages of high safety, precise positioning, and high work efficiency, but also has the disadvantages of heavy weight
The weight conference has some disadvantages, such as: high energy consumption, relatively slow speed, etc.

Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0024] This embodiment provides a heavy-duty AGV frame lightweight design method based on finite element analysis, the specific steps are as follows:

[0025] Step S100, using the mid-surface extraction function panel of the hypermesh software to perform a mid-surface extraction operation on the original frame model. In order to simplify the model and reduce the amount of calculation, necessary geometric cleaning is performed on the model after mid-surface extraction; finally, automatic mesh division and mesh quality inspection are performed on the frame, such as figure 2 shown.

[0026] In step S100, specifically include:

[0027] Step S101, performing mid-plane extraction on the original frame model. Since the length and width of the frame are far greater than the ...

Abstract

The invention discloses a heavy-load AGV frame lightweight design method based on finite element analysis, and the method comprises the steps: carrying out t mid-plane extraction of an original framemodel, carrying out geometric cleaning in order to simplify the model and reduce the calculation amount, and carrying out grid optimization of a bigger hole; and finally, conducting automatic mesh generation on the whole frame, mesh quality inspection and further conducting processing on meshes with the quality not meeting the requirement; applying a material and component connection mode meetingindustrial requirements to the frame model; after the above model is established, applying a static load to the model, analyzing rigidity and strength changes under different working conditions and providing a basis for lightweight design; under the condition that the frame meets the strength and rigidity requirements, selecting independent variables, constraint conditions and a target function, and finally performing size optimization by using INSIGHT commercial software. The lightweight design of an AGV frame is realized based on finite element analysis, and the manufacturing cost is saved under the condition of meeting the industrial actual application scene.

Description

technical field [0001] The invention relates to the field of lightweight design of vehicle frames, in particular to a design method based on finite element analysis. Background technique [0002] With the development of economic globalization and the development of port free trade, the port container transportation industry has entered a period of rapid development. The original trailer operation can no longer meet the needs of the current port. Therefore, the heavy-duty AGV came into being. It is a handling equipment for container terminals equipped with automatic guidance systems. Compared with the handling equipment of traditional container terminals, It has the advantages of high safety, precise positioning, and high work efficiency, but also has the disadvantages of heavy weight. The weight conference has some disadvantages, such as: high energy consumption, relatively slow speed and so on. Therefore, it is imperative to carry out lightweight design for heavy-duty AGV...
