摘要
使用ANSYS有限元分析软件对桥梁施工卸落设备?砂筒进行了空间应力及变形分析,分别比较了筒底部受约束和自由两种工况的分析结果,对某一实际工程使用的沙筒进行了足尺模型试验,通过分析比较试验和计算结果,指出了目前普遍使用的设计计算方法存在的问题,并提出了设计砂筒的简化计算公式.
Space stress and deformation of sand barrel used in the bridge construction are analysed by using ANSYS FEM software. The results of two cases of both of the bottom frxed and the bottom free are compared. The full size mode of sand-barrel used in certain practical project is tested. According to compare the test result and calculating result, some valuable suggestion are provided and a simple evaluating formation is presented.
