The invention discloses a magneto-rheological shock absorber fatigue testing method and system. The method comprises the following steps: selecting any current value in the current range interval as the current testing current value, selecting any unit volume accumulative dissipation energy value in the current dissipation energy range interval as the current unit volume accumulative dissipation energy testing value; at the preset temperature, obtaining an indicator diagram of the magneto-rheological shock absorber according to the current testing current value and the periodic vibration excitation value; determining the single-period dissipation heat according to the indicator diagram; computing the testing period number according to the single-period dissipation heat and the current unitvolume accumulative dissipation energy testing value; judging whether the testing period number is in the preset period range; if the testing period number is located in the preset period range, ending the testing; if the te
