摘要
Abstract
In order to improve the bearing capacity and stability of agricultural greenhouses,structural static analysis and optimization of the greenhouse skeleton under wind and snow load were conducted.Firstly,the wind load and snow load were calculated.Secondly,the finite element model of the greenhouse skeleton was established to analyze the characteristics of deformation and stress of the skeleton under extreme wind load,snow load,and coupling load of wind and snow.Finally,the structural optimization of the greenhouse skeleton was simulated by changing the angle between the side column of the greenhouse and the ground.The results show that the comprehensive mechanical performance of the greenhouse is best when the angle between the side column and ground is 82°.The carrying capacity and stability of the greenhouse are improved after optimization,which can provide a reference for engineering applications.关键词
