摘　　要：鱼雷产品使用的橡胶密封件由于受热、氧、应力及工作介质等因素的作用,随时间的推移会发生老化变质,使工作性能下降或密封失效,而鱼雷产品对密封性有很高的可靠性要求,评估鱼雷产品橡胶密封件在装配状态下的贮存期有十分重要的意义。通过对橡胶材料及密封件加速老化试验,评估了橡胶材料密封件在一定置信度下的贮存期。As time pass by,the effect of heat, oxygen and working medium on the torpedo rubber seal will make it deteriorated. This will cause the degradation of the processing performance or seal failure. Torpedo need high functional reliability for seal performance, so the evaluation of torpedo rubber seal storage period under assembly state is very important. In this article, by the accelerated life test, evaluating four different rubber material seal storage period under a certain confidence level.
