Sunlight Greenhouse H Section Steel Frame Design And ANSYS Analysis

With the development of solar greenhouse plant economy in north rural area of china, the steel framework of solar greenhouse is applied more and more.Through investingating, the typical form and structrure parameters of solar greenhouse steel framework are unreasonable. Using the method of finite element and ANSYS analysis, the changes of bearing capacity and deformation characteristics of the solar greenhouse steel framework under the biggest combination load with four kinds of curve framework are analyzed. Spread curve framework at present had the best mechanics function, the diformation and stress of the spread curve framework is lowest. Parameter 1|7 the power function curve framework mechanics function is most bad, the diformation and stress is most highest. The largest of all the skeleton deformation is 0.055998m and it is less than the allowable deformation of curved beams wich is 0.09m.The maximum stress is 173 MPa and it is less than the yield limits stress of glasshouse framework wich is 235MPa.Comparied with the framework with strengthen beam we get a conclusion that strengthened beam can effectively improve the mechanical properties of the greenhouse frame, we find that greenhouse frame made by number 100x50 narrow flange rolled H section steel meets safety requirements while use materials at least, the economy and security to achieve unity.The work done in this paper can be as reference for design and facture of the solar greenhouse steel skeleton in shanxi.
