基于FMECA的某型船舶报警系统的故障分析

摘要

为了提高某型船舶报警系统的可靠性，首先对报警系统进行了FMECA分析，明确了系统设计中存在的潜在隐患；然后通过可靠性强化试验，暴露了系统设计中的缺陷和薄弱部分。可靠性强化试验的结果和系统FMECA分析的结果相吻合，二者的结合为提高系统的可靠性提供了改进方法和措施。%In order to improve the reliability of a certain ship alarm system,failure modes effects and criticality analysis (FMECA) for the alarm system are conducted to clear and definite the potential risk existing in system design,and then the weak links and defects of system design are found out through the reliability enhancement testing(RET). The results of FMECA and RET are consistent with each other. The combination of them provided a method to improve the reliability of alarm system.
