主要介绍国外内对寿命预测的研究，并对预测理论进行说明；对目前橡胶隔振器用胶料进行不同温度下的热老化试验，根据国标GB/T 20028-2005对该橡胶的寿命进行预测，提出该胶料的使用寿命约12年半，但橡胶隔振器中橡胶静态下的压缩变形应不超过橡胶厚度的15%；故该实验方法不适合于橡胶隔振器寿命的预测。
主要介紹國外內對壽命預測的研究，併對預測理論進行說明；對目前橡膠隔振器用膠料進行不同溫度下的熱老化試驗，根據國標GB/T 20028-2005對該橡膠的壽命進行預測，提齣該膠料的使用壽命約12年半，但橡膠隔振器中橡膠靜態下的壓縮變形應不超過橡膠厚度的15%；故該實驗方法不適閤于橡膠隔振器壽命的預測。

Researches of lifespan prediction of rubber vibration isolators were introduced. The principle for lifespan prediction was illustrated. Thermal aging life of a currently-used vibration isolation rubber material was tested at different temperatures. Its aging life was predicted according to GB/T20028-2005 standard. The results show that the aging life of the material is 12.5 years at 25℃. But static contraction of the rubber component in the rubber isolators should be less than 15%of the rubber thickness. So, it is concluded that this experimental method is not suitable for the lifespan prediction of the rubber isolators.
