海洋平台常因油气泄漏而引发爆炸和火灾事故，对平台结构和工作人员的安全造成严重威胁。本文以某海洋平台密闭舱室为研究对象，使用MSC.Dytran对海洋平台在爆炸和高温载荷作用下的动态响应进行数值模拟。分别从结构的毁伤变形、冲击环境和能量吸收等方面研究平台结构在爆炸和高温载荷作用下的损伤机理和动态响应规律，为海洋平台的设计和建造提供参考依据。
The Explosion and fire accidents are often caused by oil and gas leakage on offshore platforms, which pose a serious threat to the safety of platform structures and staff. In this paper, the closed compartment of a certain offshore platform is used as the research object, and the dynamic response of the offshore platform under the effects of explosion and high temperature loads is numerically simulated using MSC. Dytran. The damage mechanism and dynamic response law under the action of explosion and high temperature load provide a reference basis for the design and construction of offshore platforms.
