密封铅酸蓄电池耐振性能的研究

在研制 6FM 10 0密封铅酸蓄电池的过程中 ,发现蓄电池的耐振性能达不到指标要求 ,经解剖后发现断裂主要产生于极柱与汇流排的交汇处。分析其失效原因为铅合金在外力作用下 ,产生塑性变形引起的低周疲劳 ,造成断裂。为避免破坏的发生就应尽量减少铅合金的塑性应变 ,由此我们总结出几种提高蓄电池耐振性能的方法。 6FM 10 0密封铅酸蓄电池采用一体型抗振支柱 ,使其振动性能大大提高。这些方法对提高密封铅酸蓄电池耐振性能的整体水平都将是极为有益的。

Study on vibration-resistant property of sealed lead-acid batteries

In the research of 6 FM 100 sealed lead-acid battery for military use,we found that its vibration-resistance property was lower than standard requirement.By means of dissection,the fracture was found at the cross of strap and post.Through analysis,the failure reason was confirmed as that the low cycle fatigue caused by plastic deformation occurred in the lead alloy,thus the fracture occurred.We have summarized several methods for improving the vibration-resistance propetry.The integrated vibration-resistance strut,one of the methods was adopted by the 6 FM 100 sealed lead-acid battery.All the methods we introduced are beneficial to improve the overall level of vibration-resistance property for sealed lead-acid battery.
