The invention relates to a testing apparatus for anti-vibration performance of a converter valve, and a testing method thereof. The testing apparatus for anti-vibration performance of a converter valve, and the testing method thereof are used for realizing that a converter valve module simulates the vibration working condition being similar with the field operation working condition under the condition without applying high voltage and heavy current. The testing method comprises test product converter valve module support method selection, vibration source parameter calculation, and vibration point selection method for the test product converter valve module. The testing method can simulate the vibration working condition during the operating process of the converter valve module under the condition without applying high voltage and heavy current, and can provide great convenience for researching the anti-vibration characteristic of a converter valve pole plate and other elements.
