爆炸载荷作用下玻璃钢防护结构破坏分析

Research on Failure of Fiberglass Protective Structure under Explosive Load

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。

The explosion process of spacecraft separation device is simulated and validated. The test and constitutive parameter calibration methods of dynamic mechanical performance of fiberglass protective structure are presented,and the failure process of fiberglass protective structure is analyzed. The analysis results show that the tensile failure and shear strength failure under explosive load are the main forms of the fiberglass protective structure damage.
