摘要:

针对电连接器用G100硅橡胶绝缘件在长期贮存条件下的可靠性建模问题,从微观层面分析并揭示了其绝缘电阻下降的主要原因是环境温度和湿度引起了材料基体大分子基团发生氧化和水解反应;基于分子动力学和质量作用定律,分析了在温度和湿度影响下G100硅橡胶载流子浓度的变化,建立了G100硅橡胶失效物理模型;结合中心极限定理,构建了G100硅橡胶绝缘件贮存可靠性模型;利用A-D(Anderson-Darling)检验法和拟合优度检验法,结合扫描电镜和傅里叶变换红外光谱仪,验证了所构建模型的正确性和合理性。研究结果为电连接器用G100硅橡胶在长贮条件下的绝缘可靠性评估提供了理论基础。

Abstract:

Focusing on the reliability modeling of G100 silicone rubber insulation parts for electrical connector under long-term storage conditions, this study analyzed and revealed at the microscopic level that the primary cause of insulation resistance degradation was the oxidation and hydrolysis reactions of polymeric molecular groups in the material matrix induced by environmental temperature and humidity. Based on molecular dynamics and the law of mass action, the change of the carrier concentration of G100 silicone rubber under the effect of temperature and humidity was analyzed, and a physical model for the failure of G100 silicone rubber was established. By applying the central limit theorem, a storage reliability model for G100 silicone rubber insulation part was constructed. The validity and rationality of the constructed model were verified through A-D (Anderson-Darling) and goodness-of-fit tests, supported by scanning electron microscopy and Fourier-transform infrared spectroscopy. The research results provide a theoretical foundation for evaluating the insulation reliability of G100 silicone rubber for electrical connector under long-term storage conditions.
