【摘要】:對航天器分離裝置的爆炸作用過程進行了數(shù)值模擬研究和試驗驗證。探討了玻璃鋼防護結(jié)構(gòu)動態(tài)力學(xué)性能測試和本構(gòu)參數(shù)標定方法,并對玻璃鋼防護結(jié)構(gòu)的破壞作用過程進行了分析。分析結(jié)果表明,在爆炸載荷作用下拉伸破壞和剪切強度破壞是玻璃鋼防護結(jié)構(gòu)破壞的主要形式。
[Abstract]:The explosion process of spacecrafts is simulated and verified by experiments. The dynamic mechanical properties of FRP protective structure and the calibration method of constitutive parameters are discussed, and the failure process of FRP protective structure is analyzed. The results show that tensile failure and shear strength failure are the main failure forms of FRP protective structure.
