摘要

防爆箱是石油钻采设备安全的保障,采用有限元方法分析防爆箱的防爆性能可以避免爆炸试验的高昂花费并极大地缩减开发周期。计算了爆炸冲击波作用下防爆箱各部分所承受的冲击载荷,考虑材料非线性,基于MSC Nastran SOL400高级非线性分析模块对防爆箱进行瞬态动力响应分析,获得各部分在爆炸冲击下的行为,并分别进行校核。研究结果可以为防爆箱的设计开发、结构优化提供参考。

Abstract

Explosion-proof box is used for the protection of petroleum drilling equipment. Costly explosion experiments will be avoided and the development cycle will be greatly reduced if finite element method is chosen for the analysis of explosion-proof performance. Completed the transient dynamic response analysis in nonlinear material model based on MSC Nastran SOL400 module. Do the checking after we got various parts’ behavior of explosion-proof box under blast shock. The results could be the reference of explosion-proof box’s design or structural optimization.
