Simulation and Experiment of the Influence that Interfacial Stress Sensor Leaves on Solid Motor Structure

Abstract

Real-time health monitoring system based on embedded sensor for solid rocket motor can accomplish real-time monitoring on the health situation of motor. It has become one of the key research subjects of solid rocket motor area in recent years. According to the key problems of research and development of the real- time health monitoring system for solid rocket motor, this paper applied the method combining numerical simulation and experiment research in studying the influence that interfacial stress sensor leaves on solid rocket motor structure. At first, it conducted numerical simulation on the influence that interfacial stress sensor embedding leaves on the structure of solid rocket motor. Then, it used self-made adhesive bonding pieces with embedded sensors to conduct experiment on adhesive bonding strength under natural storage environment, and obtained the law of the influence that interfacial stress sensor leaves on motor structure.
