Forward design method of photovoltaic panel steel frame structure

Abstract

The invention relates to the field of photovoltaic technology, and provides a forward design method of a photovoltaic panel steel frame structure, which comprises the following steps: analyzing a user use environment and engineering information actually required by a photovoltaic panel steel frame, and obtaining a target value of each working condition; generating an initial design model of the photovoltaic panel steel frame according to the plurality of target values and preset geometric information and boundary physical parameters of the photovoltaic panel steel frame; performing morphological optimization on the initial design model by using a multi-working-condition topological optimization technology and a trade-off guide weight method to obtain an initial topological optimization structure of the photovoltaic panel steel frame; and establishing an approximate parameterization model according to the initial topological optimization structure, and performing size optimization on the approximate parameterization model to obtain a target topological optimization structure of the photovoltaic panel steel frame according with the target value. By means of the forward design method, the design and production period of the photovoltaic panel steel frame structure is shortened, and cost is reduced.

Description

technical field [0001] The invention relates to the field of photovoltaic technology, in particular to a forward design method for a steel frame structure of a photovoltaic panel. Background technique [0002] The frame of the solar photovoltaic panel is made of section steel, which can greatly reduce the input cost, and the mechanical properties such as strength can also be significantly improved. However, there are very few steel frame products on the market at present. The reason is that there is no good design. As a result, the product cannot be recognized by users. [0003] At the same time, to do a good job in the design of a project, you must have rich design experience. To do a good job in positive design, you need rich design experience, which is currently relatively scarce. In the early stage of forward design, a lot of planning work is required, and the design must be continuously revised and optimized. According to the current situation in China, in order to ob...
