Starter durability test verification method and system

The invention discloses a starter durability test verification method, which comprises the following steps: taking a plurality of samples from the same batch of starters as test samples; carrying outrefitting on a test engine to simulate increased parasitic load of an accessory mounted on the engine when the starter drives the engine to rotate; assembling each test sample with the corresponding test engine, and starting the starter to carry out loop test based on a preset method, wherein in the single cycle test, starting and stopping the starter for many times according to the time sequenceto simulate different starting conditions of the starter; and judging test result of each cycle test according to preset conditions, and generating a failure probability density function curve of a test sample group according to failure cycle number obtained after ending of the cycle test to indicate durability characteristics of the batch of starters of the test samples. The method can effectively improve starter test res
