应力-强度干涉理论在战术导弹固体发动机结构可靠性评估中的应用

The Application of Stress-Intensity Interference Theory to Structural Reliability Evaluation of Tactical Solid Rocket Motors

根据某空-空导弹发动机的研制试验结果,用蒙特卡洛法进行了计算机模拟,然后再用应力-强度干涉理论进行了发动机结构可靠性评估,结果表明,模拟结果和实际结果相符,结构可靠性评估结果合理、有效。

Based on the firing test results of some air-to-air missile motor, its operation process is computer-simulated by the Monte-Carlo method, and then its structural reliability is evaluated based on the stress-intensity interference theory. The results show that the simulated results which agree well with the actual results exhibit the rational and effective structural reliability evaluation.
