摘要：Rupture disk is an important safety relief device whose bursting at set pressure is essential to protect pressure equipment. However, the existing standards and research still lack the system regularity study of the pressure rise rate on the burst pressure. And the range of the pressure rise rate is not sufficient. In this paper, a test platform with an adjustable pressure rise rate is developed, which can achieve 0-950 MPa/s pressure rise rate load. A series study of conventional domed rupture disk is conducted based on this platform. The results show that the burst pressure error is up to 44.69% with increasing pressure rise rate, significantly affecting the burst pressure. The change of burst pressure is generally an increasing trend. It is divided into three stages, showing a trend of first fast, then slow and finally fast. The reasons for the failure of the regularity of the rupture disk under different pressure rise rates are revealed from the three aspects of burst pressure, deformation behavior, and fracture morphology.
