【摘要】 利用ANSYS软件建立GIS壳体法兰的有限元计算模型,用PRETS179和PTSMESH模拟壳体法兰在有螺栓预紧力作用和没有螺栓预紧力作用下的应力分布规律,并与实验结果进行比较。结果表明,螺栓预紧力对法兰螺栓孔附近应力的分布有明显影响,离螺栓孔越近,法兰的应力集中程度越高,结果与试验一致。更多还原

【Abstract】 Using ANSYS creates finite element calculating model of GIS shell flange,flange strain distribution disciplinarian with bolt pretightening force and without bolt pretightening force is obtained by applying PRETS179 and PTSMESH and is compared with the experimental result. The bolt pretightening force has obvious influnce to the near aera of flange bolt bore,and more near the aera to bolt bore,higher flange strain concentrated degree,and the result and the experiment are consistent.更多还原
