双极性锌银贮备电池优化设计的可靠性研究

Reliability research on optimal design of bipolar silver-zinc reserve battery

围绕双极性锌银贮备电池低温脉冲负载能力不足的问题,开展了双极性锌银贮备电池的优化设计,提出了两套设计方案,同时对两套优化方案获得的低温放电数据进行了系统讨论。结果显示在显著性水平为0.01时,根据GB/T4882-2001中夏皮洛-威尔克检验方法验证两套设计方案获得的放电数据均为正态分布的;采用GJB/T376-87中计量数据估计可靠度的方法得出方案B具有较高的可靠性。最后筛选出方案B为双极性锌银贮备电池的优化方案。

The bipolar silver-zinc reserve batteries are deficient in impulsive load volt at the lower temperature. To solve this problem, two pieces of optimal design were presented and two sets of discharge data from optimal design at the lower temperature were obtained. The normality and reliability of discharge data from optimal designs were discussed systematically. The normality of discharge data was tested according to Shapiro-Wilk inspection method from GB/T4882-2001 at the remarkable level of 0.01. It is concluded that discharge data from optimal designs are normal. According to measurement data assessment method from GJB/T376-87, reliability assessment of optimal designs were conducted and design B possessed higher reliability .Thus design B was screened as the optimal design.
