【摘要】 有“工业血液”之称的石油对世界经济的影响举足轻重,目前人类对石油的依赖是其它能源无法替代的,因此,各国加大了石油的战略储备。从储罐的设计、建造和使用情况看,采用大容量储罐储油具有节省钢材、减少占地面积、方便操作管理和节省投资等优点,储罐的大型化成为发展的必然趋势。但已建成的储罐都是从提高钢材性能入手,使储罐向大型化发展,并未改变其结构形式。2009年,张文福提出一种新的储罐结构形式——网壳储罐,此结构可以充分利用网壳的抗拉、抗弯性能好的特点,有效地减少底板和罐壁的板材厚度,降低造价,且具有外观独特、优美,视觉效果好等优点。本文将采用有限元软件ADINA,对网壳储罐的静力性能及地震响应进行研究,主要工作如下:1.验证本文所采用的全罐模型、1/4模型的合理性;2.改变网壳储罐的各种参数,进行盛水条件下的静力分析,研究各参数对其静力性能的影响;3.优化设计15×10~4m~3和30×10~4m~3网壳储罐,分析其静力特性;4.采用变点法设计30×10~4m~3普通储罐,并将15×10~4m~3和30×10~4m~3网壳储罐分别与15×10~4m~3和30×10~4m~3普通储罐进行经济性对比;5.对各状态下的普通储罐和网壳储罐进行固有振动特性分析,对比分析普通储罐与网壳储罐振动特性的差异,并研究各参数对网壳储罐振动特性的影响;6.对经优化设计的15×10~4m~3网壳储罐,分别输入4种地震波,进行地震响应分析。更多还原

【Abstract】 As the industrial blood, oil has great influence on the world economy. At present, humanity’s reliance on oil is unable to be substituted by any other energy sources, all countries therefore increased strategic petroleum reserves. From the perspective of tank design, construction and usage, building large capacity storage tank can save steel, reduce floor space, easy operation and management and decrease investments, to build large capacity storage tank is the inevitable trend of development. But tanks have been built are all starting from improving the performance of steel to make tank to the large-scale development, the structure form hasn’t been changed. In 2009, Wenfu Zhang put forward a new tank structure——storage tank with latticed shell (STLS), it can make full use of latticed shell tensile strength and its good flexural performance, effectively reduce thickness of bottom plate and tank shell, and reduce cost, have the unique and beautiful appearance, good visual effect, etc.This paper will study on the static behavior and earthquake response of STLS by using ADINA finite element software, and the main work is as follows:1.To verify total tank model and 1/4 tank model’s rationality.2.To change parameter of STLS, and research influence of parameter on its static behavior.3.To optimize the 15×10~4m~3 and 30×10~4m~3 STLS, and analyze their static behavior.4.To design 30×10~4m~3 common storage tank by the variable point method, and compromise the 15×10~4m~3 and 30×10~4m~3 common storage tank respectively with the 15×104 m3 and 30×10~4m~3 STLS on economic.5.To study on natural vibration characteristic of common storage tank and STLS under different conditions, comparative analyze the difference of the two type of tanks, and study the influences of the parameters on natural vibration.6.To study on the earthquake response of the optimized 15×10~4m~3 STLS under 4 kinds of earthquake waves.更多还原
