| 目的 研究固体发动机药柱头部人工脱粘层在50， 20， -40 ℃等3种温度下的应力应变。方法基于线性粘弹性有限元方法， 利用ABAQUS分析软件对药柱应力应变进行仿真。结果 得到了人工脱粘层在3种温度条件下的Mises和最大主应力应变云图， 及Ⅰ， Ⅱ界面轴向、 周向和径向的应力应变对比曲线。结论 最大应力应变出现在人工脱粘层根部， 应力与环境温度的变化成线性关系， 温度变化对Ⅰ界面上脱粘层轴向应变、 Ⅱ界面上径向应变影响最大。 |

| Objective To study the stress and strain of artificial debond layer of solid engine propellant head at 50,20 and -40℃. Methods Based on the linear viscoelastic finite element method, we carried out simulation analysis ofthe stress and strain of the propellant using ABAQUS software. Results The Mises and the maximum principalstress-strain contours of the artificial debond layer at three temperatures, as well as theⅠ, Ⅱ interfacial axial, radial andcircumferential stress-strain contrast curves were obtained. Conclusion The maximum stress and strain occurred at thebottom of the artificial debond layer, and the stress had a linear relationship with the change of environmentaltemperature. The temperature change had largest influence on the Ⅰinterface axial strain and the Ⅱinterface radial strain. |
