铝合金储煤仓结构性能分析
|
摘要
以新疆烟墩物流园球面铝合金原煤储煤仓为研究对象,采用结构分析软件SAP2000、通用有限元分析软件ANSYS,对结构的静力性能、动力性能、杆件稳定性及结构整体稳定性进行分析,得到该结构在极限状态荷载效应组合下的位移、应力、自振频率、杆件稳定性及非线性荷载因子。分析结果表明:储煤仓结构刚度、强度和稳定性均满足设计要求。
The study focused on the sphere aluminum alloy coal storage bunker of Xinjiang Yandun Logistics Park,using structural analysis software SAP2000 and large general- purpose finite element analysis software ANSYS,analyzed its dynamic characteristic,static characteristics stability of the pole and overall structure,obtained the displacement,stress,natural vibration frequency and stability of the bunker.The results of analysis showed that the stiffness,strength and the stability of the aluminum alloy coal storage bunker all meet the specification requirements of design.
