带助爆环锥的微型反拱爆破片快速加压失效机理与影响因素研究
Failure mechanisms and influencing factors of miniature reverse arch bursting discs with booster ring cones under rapid pressurization
摘要
Abstract
To investigate the failure mechanism and influencing factors of bursting pressure for reverse arch bursting discs with booster ring cones under rapid pressurization,numerical simulations of the bursting process were conducted alongside burst tests,examining the influence of structural parameters on bursting pressure.Research results show that the bursting process of reverse arch conical bursting discs comprises four stages:stable compression,root collapse,high-speed flipping-piercing,and high-speed flipping-tearing.Among these,root collapse is primarily induced by compressive membrane forces.After root collapse,the disc loses stability and initiates high-speed flipping.Upon contacting the booster ring cone,membrane forces and shear stresses in the contact area rapidly exceed the yield limit,resulting in tensile-shear mixed failure.Bursting pressure is significantly influenced by disc arch height,thickness,and diameter,but minimally affected by booster cone structural parameters.Bursting pressure decreases with increasing arch height and diameter,while increasing substantially with greater thickness.The research results can provide a theoretical basis for the optimal design and engineering application of the reverse arch bursting disc structure.关键词
