目的 研究可靠性强化试验技术在全压智能探头研制过程中的应用。方法 通过对受试产品施加单一或综合的环境应力, 快速激发出产品的潜在故障, 并对故障现象进行原因分析、失效模式分析, 进而提出改进措施以提高产品的可靠性。以某型机载全压智能探头的可靠性强化试验为例, 通过制定相应的试验方案, 并阐述了试验实施的整个过程, 最后对试验结果进行了评价, 并提出了改进方案以提高产品的可靠性, 在回归验证试验中证明了改进意见以及改进措施的有效性。结果通过强化试验, 在短时间内获得了产品高低温及振动的工作极限应力值, 并发现了在其他可靠性环境试验中无法发现的潜在故障, 向产品研制单位提供了针对薄弱环节的改进意见, 使产品的可靠性得到定性地增长。结论 通过对典型产品进行系统级可靠性强化试验的实施与试验结果分析, 给出了同类产品进行可靠性强化试验的典型案例和实施步骤。 |

Objective To investigate the application of reliability enhancement testing in development of airborne pressure probe.Methods Reliability enhancement testing is a test method which has been widely used in the aerospace field recently. Testing product was applied to single or combined environmental stresses, so as to quickly stimulate potential failure, and analysis failure phenomena and failure mode; in addition, further improvement measures were proposed to improve product reliability.ResultsThis article used an Airborne pressure probe as an example to develop a test program, described the entire process, evaluated the results of the program and improvement of the product reliability. Conclusion A typical case of strengthen reliability testing and implementation procedures were provided based on the system-level reliability enhancement testing analysis of a typical product. |
