| 中文摘要: |
| 以某动力电池氟橡胶密封圈（简称氟橡胶密封圈）的压缩永久变形为老化指标，对氟橡胶密封圈在3个温度（85，100，和120?℃）及2个初始压缩率（25%和40%）下进行加速老化试验，以评估氟橡胶密封圈的贮存寿命可靠性。根据加速老化动力学方程式得到氟橡胶密封圈在温度为80?℃和初始压缩率为25%下静密封贮存寿命为38.22 a。 |
| 英文摘要: |
| Using the compression set of a certain power battery fluororubber sealing ring（referred to as fluororubber sealing ring） as the aging index，accelerated aging tests were conducted on the fluororubber sealing ring at three temperatures（85，100 and 120 ℃） and two initial compression rates（25% and 40%） to evaluate the reliability of storage life of the fluororubber sealing ring.According to the accelerated aging kinetic equation，the static sealing storage life of the fluororubber sealing ring at a temperature of 80 ℃ and an initial compression rate of 25% was 38.22 a. |
