摘要:
本实验以1 200 mm×8 00 mm×2 000 mm预应力实验结构为研究对象,制成500 mm×250 mm×2 000 mm的304白钢内罐,通过连续注入-196℃液氮,采用实验和ANSYS Workbench软件仿真模拟两种方法,获得动态泄漏过程温度场和应力场分布,探寻温度场和应力场分布变化规律。结果表明:在整个泄漏实验过程中混凝土结构温度先略有上升,随后温度迅速降低至平衡,待储罐低温液体挥发后温度极其缓慢回升至原温度场;在数值仿真分析中,随着储罐内泄漏液面不断升高,实验混凝土结构温度场温度迅速降低,等效应力场急速增大;低温液体泄漏液面升高时,混凝土结构温度与混凝土测点距储罐水平距离呈五次多项式定量关系。
Abstract:
In the experiment, the experimental structure of 1 200 mm×800 mm×2 000 mm pre-stressed concrete is studied as the research object, 304 stainless steel tank structure of 500 mm×250 mm×2 000 mm is made as inner tank, through a continuous injection of -196℃ liquid nitrogen, the experiment adopts two methods of experiment and ANSYS Workbench software simulation to obtain the dynamic distribution of the temperature field and stress field of the leakage process, and explore the temperature field and stress field distribution. Results show that in the whole process of leakage, first of all, the temperature of experimental concrete structure rises slightly, then quickly reduces to the balance, after large amounts of storage tank liquid volatile, extremely slowly rises back to the original temperature field; In numerical simulation analysis, when the level height of storage tank liquid rises, concrete structure temperature field quickly decreases, and equivalent stress field of concrete structure rapidly decreases; When the level height of storage tank liquid rises, the temperature of concrete structure and the horizontal distance between the concrete temperature detection point and inner tank are the relations of five times polynomial.
