摘要
为分析波纹板结构在气云爆炸荷载下抗爆性能,减少爆炸事故中人员伤亡及财产损失,建立了基于Johnson-Cook模型和CONWEP控制方程的波纹结构数值仿真模型,并通过气体爆炸试验验证了仿真模型的准确性.通过调整波纹板厚度、坡深、波宽等参数,分析波纹结构在气体爆炸下动态响应规律.结果表明,波纹板变形量与波纹板厚度t、坡深h呈负相关,与波宽L1、坡宽L2呈正相关,其中,受厚度t的影响最为显著,坡深h次之,波宽L1、坡宽L2较小.研究结果可为高性能波纹结构抗爆设计提供技术支撑.
Abstract
In order to analyze the anti-explosion per-formance of corrugated structure under gas cloud explo-sion load and reduce the casualties and property losses in explosion accidents,a numerical simulation model of corrugated structure based on Johnson-Cook model and CONWEP governing equation was established,and the accuracy of the simulation model was verified by gas ex-plosion test.By adjusting the parameters of corrugated plate thickness,slope depth and wave width,the dy-namic response of corrugated structure under gas explo-sion was analyzed.The results showed that the deforma-tion of corrugated plate was negatively correlated with thickness t and slope depth h,and positively correlated with wave width L1 and slope width L2.Among them,the influence of thickness t was the most significant,followed by slope depth h,and wave width L1 and slope width L2 were less.The research results can provide technical support for the antiknock design of high-per-formance corrugated structures.
