【摘要】 爆破片作为一种常用的安全泄放装置,保障其具备准确的爆破压力,及时泄放压力容器内部的超压是工程中十分关注的问题。本文基于自主开发的高升压速率载荷安全泄放装置平台,针对材料为Inconel600与SA316L的两种爆破片开展试验研究,对比研究高升压速率载荷下材料性能差异对爆破性能的影响。研究表明,高升压速率下材料性能变化仅影响爆破压偏差大小,不影响爆破片爆破压变化趋势与各阶段的升压速率变化区间范围。材料的塑性变形能力越强,高升压速率下的爆破压偏差值越大。更多还原

【Abstract】 As a commonly used safety relief device,the rupture disc ensures that it has accurate burst pressure,and the ability to release the overpressure inside the pressure vessel in time is a matter of great concern in engineering.This paper is based on the self-developed overpressure relief device platform that can realize high pressure rise rate load.The experimental study on Inconel600 and SA-316 L rupture disc are carried out.The difference of material properties on burst performance are studied.The results show that the change of material properties only affects the burst pressure deviation,and does not affect the trend of burst pressure and pressure rise rate range.The stronger the plastic deformation ability of the material,the greater the burst pressure deviation at high pressure rise rate.更多还原
