The invention provides a micro-vibration vibration isolator accelerated life test method and system. A vibration isolator is mainly characterized by using silicone rubber as a main bearing unit. Thiskind of vibration isolator accelerated life test method is not available in the prior art. The method is characterized by determining that accelerated life test comprises accelerated fatigue test andaccelerated aging test according to major factors influencing the service life of a vibration isolator; in the accelerated life test process, determining conditions of the accelerated fatigue test andthe accelerated aging test respectively according to relevant formulas; and carrying out function and performance test on the vibration isolator before and after relevant test and in the test to judge whether the vibration isolator can meet working requirements and determine that the vibration isolator can meet low-long life service requirements. The method fills the blank of this kind of devicelife test method, can ensure that in-orbit normal working life of the type of device can be known through the accelerated life test, and can effectively reduce life test time, improve ground life testefficiency and reduce ground life test cost.
