【摘要】：為了獲得在典型空腔內(nèi)發(fā)生爆炸后,結(jié)構(gòu)壁面上爆炸載荷的分布規(guī)律和空腔結(jié)構(gòu)的破壞形式,以國防工事和人防工事的等級設(shè)計規(guī)范為依據(jù),設(shè)計了長方體單腔室空腔模型,并對該模型進(jìn)行了藥量逐漸遞增直至可使結(jié)構(gòu)破壞的內(nèi)爆炸實驗。用壓力傳感器和加速度傳感器分別記錄了單腔室壁面上爆炸載荷的壓力時程曲線和結(jié)構(gòu)壁面振動的加速度時程曲線,分析了壁面上爆炸載荷的分布規(guī)律以及模型結(jié)構(gòu)的破壞形式,并將首個峰值的實測數(shù)據(jù)與理論計算和數(shù)值模擬結(jié)果進(jìn)行了對比,探討了3種研究方法產(chǎn)生誤差的原因。
[Abstract]:In order to obtain the distribution law of explosion load on the wall of the structure and the failure form of the cavity structure after the explosion occurred in the typical cavity, a cuboid single chamber cavity model was designed based on the grade design code of national defense and civil air defense. An internal explosion experiment was carried out on the model, in which the charge was gradually increasing until the structure could be destroyed. The pressure time history curve of explosion load on the wall of a single chamber and the wall vibration of the structure were recorded by pressure sensor and acceleration sensor, respectively. Dynamic acceleration time history curve, The distribution law of explosion load on the wall and the failure form of the model structure are analyzed. The experimental data of the first peak value are compared with the theoretical calculation and numerical simulation results, and the causes of the errors in the three research methods are discussed.
