Photovoltaic herbal medicine greenhouse static simulation method

Abstract

The invention relates to a photovoltaic herbal medicine greenhouse static simulation method. The method includes: on the basis of engineering CAD (computer aided design) drawings, adopting three-dimensional software SOLIDWORKS for establishing a three-dimensional geometrical model of a photovoltaic herbal medicine greenhouse, and saving as an STP-format geometrical model; importing the STP-formatgeometrical model; subjecting the greenhouse model to mid-surface treatment; defining material attributes of the photovoltaic herbal medicine greenhouse; subjecting the greenhouse model to mesh generation, and applying a static load according to design specification requirements; taking gravity factors to integrally add standard earth gravity to the greenhouse model; constraining degrees of freedom of light steel connectors on the bottom face of the greenhouse according to design specification requirements; operating calculation for solution; adding stress and deformation results, and checkingcorresponding cloud charts. The photovoltaic herbal medicine greenhouse static simulation method has advantages that greenhouse stress and deformation conditions can be accurately and quickly calculated, analysis time is saved, analysis efficiency is improved, and capabilities of meticulous checking and quantization of details such as greenhouse connection, parts and the like are achieved.

Description

technical field [0001] The invention relates to a static force simulation method for a photovoltaic herb shed, in particular to a static force simulation method for a photovoltaic herb shed. Background technique [0002] Photovoltaic herb shed is a new type of photovoltaic agricultural greenhouse developed according to market demand. It has the advantages of low cost and convenient installation. However, the calculation of the structure of this type of greenhouse is complicated and requires a long design check cycle. The design of photovoltaic herb sheds must comply with the "Code for Design of Steel Structures".

[0002] Photovoltaic herb shed is a new type of photovoltaic agricultural greenhouse developed according to market demand. It has the advantages of low cost and convenient installation. However, the calculation of the structure of this type of greenhouse is more complicated and requires a longer design check cycle.

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 Checking with software has the problems of cumbersome modeling, difficulty in model import, and inability to check detailed and quantified details such as the connection of the greenhouse during the analysis process. Compared with the ANSYS WORKBENCH module, the analysis of PKPM has long analysis time, Difficult and inefficient problems
