发布时间：2018-09-07 19:47
【摘要】：对航天器分离装置的爆炸作用过程进行了数值模拟研究和试验验证。探讨了玻璃钢防护结构动态力学性能测试和本构参数标定方法,并对玻璃钢防护结构的破坏作用过程进行了分析。分析结果表明,在爆炸载荷作用下拉伸破坏和剪切强度破坏是玻璃钢防护结构破坏的主要形式。
[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.
