Photovoltaic single-row greenhouse static simulation method

Abstract

The present invention discloses a single-row greenhouse static simulation method, and relates to a photovoltaic single-row greenhouse static simulation method. The method comprises: based on the engineering CAD drawings, establishing a 3D geometric model of the photovoltaic single-row greenhouse by using the 3D software SOLIDWORKS, and saving the 3D geometric model as the STP format geometric model; introducing the STP format geometric model; performing mid-surface extraction processing on the greenhouse model; defining a material attribute of a photovoltaic single-row greenhouse; performing mesh generation on the greenhouse model, and applying the static load according to the design specification requirements; considering the gravity factor to add the standard earth gravity to the greenhouse model as a whole; constraining the degree of freedom of the light steel connecting piece on the bottom of the greenhouse according to the design specification requirements; running the solution calculation; and adding the stress and the deformation result, and viewing the corresponding cloud image. The method provided by the present invention has the beneficial effects that: the stress and deformation of the greenhouse type can be quickly and accurately calculated, the analysis time is saved, the analysis efficiency is improved, and the ability to meticulously and quantitatively check andcalibrate the connection, the locality and other details of the greenhouse is ensured.

[0002] Photovoltaic single-row 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 single-row 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 software checks, there are cumbersome modeling, difficult model import, and the details of the connection and local details of the greenhouse during the analysis process cannot be carefully and quantified. Compared with the use of ANSYS WORKBENCH module, the analysis of PKPM has a long analysis time. , Difficulty and low efficiency
