ANSYSWORKBENCH-based photovoltaic herbal medicine shed anti-seismic calculation method

Abstract

The invention discloses an ANSYSWORKBENCH-based photovoltaic herbal medicine shed anti-seismic calculation method, and relates to a shed anti-seismic calculation method. The method includes the steps:building a three-dimensional geometrical model of a photovoltaic herbal medicine shed by three-dimensional software SOLIDWORKS; importing the geometrical model; performing middle surface extraction on the shed model; defining material attributes of the photovoltaic herbal medicine shed according to engineering drawing requirements; dividing grids of the shed model; performing shed building seismic analysis on a steel framework model; applying seismic acceleration spectra; setting 50 time sub-steps for loading the seismic acceleration spectra; adding standard earth gravity to the whole shed model; constraining the degree of freedom of shed bottom light steel connectors; performing solving calculation; adding stress and deformation results and checking corresponding cloud charts. Compared with PKPM and other finite element software analysis methods, the method has the advantages that analysis time can be effectively saved under equal working conditions, analysis efficiency can be improved, and shed connection and meticulous checking and quantization capacity for details such as local parts can be achieved.

Description

technical field [0001] The invention relates to an anti-seismic calculation method for a greenhouse, in particular to an anti-seismic calculation method for a photovoltaic herb shed based on ANSYS WORKBENCH. Background technique [0002] Photovoltaic herb shed is a newly developed photovoltaic agricultural greenhouse according to market demand. It has the advantages of low cost and convenient installation, but the calculation of the structure of this type of greenhouse is more complicated. The design of photovoltaic herb sheds must comply with the "Code for Design of Steel Structures". According to the PKPM steel structure technical conditions issued by China Building Science and Technology, the greenhouses must meet the conditions of use under static load conditions. At this stage, engineers and technicians usually use PKPM The software is checked, and the modeling is cumbersome, and the model is difficult to import. During the analysis process, the connection and local det...

[0002] The photovoltaic herb shed is a photovoltaic agricultural greenhouse newly developed according to market demand, which has the advantages of low cost and convenient installation, but the calculation of the structure of this type of greenhouse is more complicated

The design of photovoltaic herb sheds must comply with the "Code for Design of Steel Structures". According to the PKPM steel structure technical conditions issued by China Building Science and Technology, the greenhouses must meet the conditions of use under static load conditions. At this stage, engineers and technicians usually use PKPM The software is checked, and the modeling is cumbersome, and the model is difficult to import. During the analysis process, the connection and local details of the greenhouse cannot be checked carefully and quantified. Compared with the ANSYS WORKBENCH module, the analysis of PKPM has long analysis time and great difficulty. ,low efficiency
