摘要
为探究爆炸荷载作用下高强钢丝编织结构夹芯板的响应过程,在实爆试验的基础上,采用有限元方法,分析高强钢丝编织结构夹芯板的响应过程,对比不同芯层高度夹芯板的响应模式;研究不同芯层参数对于高强钢丝编织结构夹芯板抗爆性能的影响规律;根据无量纲冲量与无量纲变形量的计算公式,进一步推导高强钢丝编织结构夹芯板的设计指导公式。试验及数值模拟结果表明:当面板、荷载以及材料参数固定时,高强钢丝编织结构的芯层高度选取在58~78 mm为宜,且在此区间内,芯层高度越高夹芯板抗爆性能越好,偏折角越小夹芯板抗爆性能越好。研究可为高强钢丝编织结构夹芯板抗爆性能的优化设计提供参考。
In order to explore the dynamic response of high-strength steel wire woven structure sandwich panels under explosion load,the finite element method was used to study the response process of high-strength steel wire woven structure sandwich panels on the basis of explosion test.The response models of sandwich plate with different height of core layer were compared.The effects of different core parameters on the anti-blast performance of high-strength steel wire woven structure sandwich panels were analyzed.According to the calculation formula of dimensionless impulse and dimensionless deformation,the design guide formula of high-strength steel wire woven structure sandwich panels was derived.The experimental and numerical simulation results show that:it is appropriate to select the core height of high-strength steel wire woven structure between 58 mm and 78mm under the condition of constant panel,load and material parameters.Within this interval,the higher the core layer height and the smaller the deflection angle,the better the anti-blast performance.The research can provide reference for the optimization design of anti-blast performance of high-strength steel wire woven structure sandwich panels.
