| 中文摘要: |
| 当火箭弹的数量较少或造价昂贵时，针对各部组件试验信息多而系统级产品信息较少，无法准确有效实现系统可靠性综合评估的问题，给出基于CMSR的由部组件试验信息向系统级试验信息等效的折合方法，并与系统级试验信息融合，从而实现可靠性评估。综合考虑储存期间部组件检测试验的试验数据，利用CMSR方法实现部组件试验信息向系统级试验信息的折合，综合系统级试验数据，最终实现可靠性评估。在不同置信度下，系统综合火箭弹部组件试验数据和系统级试验数据，给出火箭弹储存多年后的任务可靠度，为火箭弹能否继续服役使用提供支撑。针对系统试验数据少或无试验数据的情况下，利用部组件的试验信息折算成系统级试验信息，利用成败型可靠性计算公式，可求取储存一定年限后系统级产品的任务可靠度。 |

| When the number of rockets is small or the cost is high, the test information of each component is much and the system-level product information is less. It is difficult to realize the comprehensive assessment of system reliability accurately and effectively. Give the equivalent conversion method from component test information to system-level test information based on CMSR. Integrate the system-level test information to achieve reliability evaluation. Consider the test data of the component inspection test during storage Comprehensively. Realize the conversion of component test information to system-level test information based on the CMSR method. Integrate the system-level test information to achieve reliability evaluation. Under different confidence levels, Considering the test data of the rocket components and the system-level test data, give the mission reliability of the rocket after many years of storage to provide the support for whether the rocket can continue to be used.In the case of little or no test data in the system, converting the test information of the components into system-level test information. Use the success-failure reliability calculation formula to calculate the mission reliability of the system-level product after a certain number of years of storage. |
