A Studay On Optimization Design Of Aquaculture Greenhouse Structure For Overwintering Fish

The research project is experimented on Aquiculture Greenhouse. Refer to the standard of greenhouse at home and abroad, on account of aquiculture greenhouse being universally used in the subtropical area of China at present, this research project expatiate the importance and necessity of structural optimization of aquiculture greenhouse. This research project analyzes the structure design of aquiculture greenhouse and the problems appeared during the production, concrete suggestion and main factors are put forward accordingly.To use the method of support structure, this research project applies the method of structural optimization which is universally used in civil and industrial building to the optimization design of aquiculture greenhouse structure. To use the theory of engineering mechanics, according to the requirement of building code, through loading analysis of the solar greenhouse, this research project determines the formula of loading,develops the calculation model, and improved by mechanics analysis with ANSYS software. The paper discusses the general process of the structure, and determines the general approach of the structural optimization for the special situation of aquiculture greenhouse. Through conducting the field tests for the optimized performance of the greenhouse, the practical results show that the strength of the greenhouse's integral structure and the ability of weather-resistant are enhanced.The research project is proposed to overcome the weakness of the common greenhouse's heat preservation characteristic, analyses the greenhouse structure's impact on the capability of collecting day lighting and preserving heat, and makes the optimal design for the heat preservation characteristic. According to the practical status of production, the research aims to minimize the construction-timber on condition that the design meets the requirement of the greenhouse's stability and strength, and designs the aquiculture greenhouse which is reasonable force loadings, saving in material, and suitable for promotion.
