Abstract: In order to realize the assembly of the solar greenhouse frame,control the installation quality,and improve the stress performance of the greenhouse frame,a new type of fabricated frame and fabricated nodes of the solar greenhouse have been designed,in order to provide new research for the fabricated sunlight greenhouse ideas.Using ANSYS Workbench software to assist in modeling and analysis,comparing and selecting two assembly methods of outer casing and inner intubation,the stress,shear and bending moment of the main pipe and casing under the action of uniformly distributed load step by step;using Workbench software to analyzes the axial stress,shear force,bending moment and deformation of the fabricated frame under the most unfavorable load.The results showed that it was concluded that in the assembly mode of the outer casing,the axial stress and bending moment of the main pipe and the casing itself were smaller and the safety was higher.Under the most unfavorable load combination,the three-section truss assembled with outer casing has a maximum axial stress of 17.35 MPa,a maximum deformation of 0.26 mm,a casing maximum axial stress of 5.0 MPa,a maximum shear force of 2 345.3 N,and a maximum bending moment of 41.3 N·m.The new prefabricated framework and prefabricated joints of the solar greenhouse are safe,stable,and small in deformation and can be popularized.
