摘要:
利用Ansys软件建立了高压开关设备用矩形槽O形密封圈模型,对该O形密封圈的变形和应力分布状 况进行了数值模拟分析,研究了其工作时的受力、变形及密封效果。对该O形密封圈在不同压缩率、不同充 气压力下的内应力及密封面接触应力分布进行了探讨,确定了仅考虑应力作用下O形密封圈材料容易失效 的位置,并得出充气压力在1.6 MPa以下时O形密封圈没有被挤入上、下法兰间隙。
Abstract:
In order to know deformation and sealing effect of O?ring with rectangular groove leakproof structure in high voltage switchgear,methods set up model for O?ring with rectangular groove leakproof structure in high voltage switchgear by ANSYS software,then the mechanical condition and deformation of the O?ring are analyzed numerical? ly. Investigate stress and contact stress distribution of O?ring with rectangular groove in different compression rate and different gas pressure. The position where the material of O?ring is easy to fail under stress is determined,and it is concluded that the O?ring is not be squeezed into gap between top and bottom flange when the inflation pressure is below 1.6 MPa. The results can provide reference for design of O?ring with rectangular groove leakproof structure in high voltage switchgear.
