| 摘要: |
| 通过热氧老化实验、声发射损伤检测实验和蠕变柔量测试实验确定HTPB复合固体推进剂非线性本构 关系,并与Schapery非线性本构方程进行比较。结果表明,含损伤老化模型较好地解释了HTPB复合固体推进剂的 非线性特性,可以应用分析HTPB复合固体推进剂的力学特性。 |

| Abstract: |
| Through heat aging experiment, AE experiment and creep experiment, the constitutive equations of HTPB composite propellant with damage and aging was presented. Compared with Schapery nonlinear constitutive equations, the equations in this paper are more simple and exact. The constitutive equations of HTPB composite propellant with damage and aging can be used to analyze the mechanical properties and explain the nonlinear characteristics of HTPB composite propellant |
