- 摘要:
- 空间推进系统可靠性评估时,采用Lindstrom-Maddens(L-M)法评估比传统方法得到的结果更高。对比分析评估数据后发现L-M法更合理,因此建议采用L-M法进行可靠性评估,可以在满足可靠性指标前提下防止对产品提出过分苛刻的要求,从而降低设计难度和减少试验费用。
- Abstract:
- When assessing the reliability of space propulsion system, the result obtained by Lindstrom-Maddens (L-M) method is much higher than by traditional method. By comparing and analyzing the data of assessment, it is revealed that L-M method is more reasonable. Therefore, the author suggests adopting L-M method in reliability assessment. Under the precondition of satisfying the reliability index, it can prevent an excessive strict demand on product, reduce the design difficulties and decrease the test cost.
