- 为实现日光温室骨架的装配化，把控安装质量，提高温室骨架受力性能，设计完成了日光温室新型装配式骨架及装配式节点，以期为装配式日光温室提供新的研究思路。利用ANSYS Workbench软件建模辅助分析，比选外套管和内插管2种装配方式，在逐级均布荷载作用下主管和套管所受应力、剪力及弯矩情况；用Workbench软件分析装配式骨架在最不利荷载作用下轴向应力、剪力、弯矩及变形情况。结果表明：骨架在外套管的装配方式下，主管及套管自身所受的轴向应力和弯矩更小，安全性更高。用外套管装配的三段桁架在最不利荷载组合作用下，最大轴向应力17.35 MPa，最大变形量为0.26 mm，套管最大轴向应力5.0 MPa，最大剪力2 345.3 N，最大弯矩为41.3 N·m。该日光温室新型装配式骨架及装配式节点安全、稳定、变形量小,可推广使用。
- 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.
