| 摘要: |
| 正交各向异性材料已在大型固体发动机上得到广泛应用。为了较大地降低发动机药柱的Von Mises应变水平，极大地提高发动机的结构完整性能，以星形药柱为例，对固体发动机药柱推进剂和绝热层的弹性模量和泊松比等正交各向异性材料参数进行了灵敏度分析，得到了固体发动机药柱正交各向异性材料参数的灵敏度系数。分析方法与结论对固体发动机的优化设计具有指导作用。 |

| Abstract: |
| The orthotropic material has been widely applied in large solid motors. In order to reduce the Von Mises strain, and greatly improve the structural integrity of solid motors, the star grain is taken as an example. The orthotropic material parameters sensitivity analysis of elastic modulus and Poisson's ratio of propellant and insulation blanket are studied. The orthotropic material parameters sensitivity coefficients of solid motor grain are obtained. The methods and conclusions are helpful for the designers, manufacturers of solid motors. |
