| 中文摘要: |
| 研究弹载控制系统长周期贮存、 高过载发射、 使用可靠性难以确定、 缺乏寿命评估方法等问题。弹载控制系统长期贮存后， 其控制系统能否承受高达20 000G的发射过载， 这直接影响其制导精度和作战效能。通过研究弹载控制系统的结构原理、 材料特性、 工艺技术， 以及其寿命与环境应力的复杂关联性， 开展高过载条件下控制系统的应力分析、 动态性能检测、 失效机理分析、 退化模型和加速模型统一形式， 以及基于多维动态序列的系统级产品可靠性研究。确定其贮存薄弱环节， 创建其在高过载冲击条件下的可靠性评估理论体系， 突破长期贮存后弹载控制系统在高过载条件下寿命评估的技术瓶颈， 拓宽弹药贮存寿命评估技术的研究范围， 为其科学定寿和维修延寿奠定基础。 |

| This paper studied the long-period storage, the high overload launch, the difficulty to determine the operational reliability, the lack of life assessment methods and other issues of the missile-borne control system. After long-term storage, whether the missile-borne control system can withstand up to 20 000G launch overload directly affects its guidance accuracy and operational efficiency. By studying the structure principle, material properties, process technology of the missile-borne control system and the complex relevance of the life and environmental stress, the stress analysis was carried out of the control system under the condition of high overload, as well as the test of dynamic performance, failure mechanism analysis, the unified form of degradation model and acceleration model, and the reliability analysis of system-level products based on multi-dimensional dynamic sequences. To determine the storage weaknesses, a systematic reliability assessment theory was established under the condition of high impact overload, which broke through technical bottlenecks of life assessment of missile-borne control system under the condition of high overload after long-term storage, broadened the scope of ammunition storage life assessment technology of artillery missile and laid the foundation for scientific life assessment and repairmen to prolonging life. |
