为研究内埋式传感器对固体火箭发动机结构完整性的影响,提出了埋入界面应力传感器的粘接试件制作方法,实验验证了该制作方法的可行性,并分析了嵌入传感器对界面粘接强度的影响。研究结果表明,所设计的试件结构、选择的胶粘剂和采用的制作方法可行,埋入传感器对粘接界面强度影响不大。为今后固体火箭发动机粘接界面嵌入应力传感器提供了技术支持。
In order to study the influence of buried sensors on the structural integrity of solid rocket motors, a method for making bonded specimens with embedded interface stress sensors was proposed. The feasibility of this method was verified by experiments and the effects of embedded sensors on interface adhesion The impact of strength. The results show that the design of the specimen structure, the choice of adhesive and the production method is feasible, embedded sensors have little effect on the bonding interface strength. It provides technical support for embedding the stress sensor in the solid rocket engine bonding interface in the future.
