以塔式太阳能热发电中的熔盐储罐为研究对象
通过数值模拟的方法
对不同液位的熔盐储罐在周向风压分布的风荷载等多种荷载组合工况下的力学性能进行研究
并依据美国ASME标准进行棘轮失效与蠕变-疲劳评定。研究结果表明:多种荷载组合工况下
在高液位(11.7和9.0 m)下应力强度最大在大角焊缝处
中低液位(6.0、3.0及1.0 m)下则在罐顶与罐壁的几何不连续处。径向位移因周向风荷载、地震响应及液压作用呈现非对称性
且径向位移受液位变化影响显著
径向位移主要集中在0°~90°迎风侧罐壁
轴向位移受影响最严重区域在罐顶中央;在不同液位下不会发生棘轮失效
且满载下不会发生蠕变-疲劳失效。
Taking the molten salt storage tank in tower solar thermal power generation as the research object
the mechanical performance of molten salt storage tanks at different liquid levels under combined load conditions such as wind load with circumferential wind pressure distribution is studied through numerical simulation
and ratchet failure and creep-fatigue assessment are carried out based on the ASME standard of the United States. The results show that under a variety of load combination conditions
the maximum stress intensity is at the large fillet weld at high liquid level (11.7 and 9.0 m)
and at the geometric discontinuity between tank top and tank wall at medium and low liquid level (6.0
3.0 and 1.0 m). The radial displacement is asymmetrical due to the circumferential wind load
seismic response and hydraulic action
and the radial displacement is significantly affected by the change of liquid level
the radial displacement is mainly concentrated in the tank wall of the windward side of 0°-90°
and the severe area affected by the axial displacement is in the center of the tank roof. No ratchet failure occurs at different liquid levels
and no creep-fatigue failure occurs at full-load operating conditions.
