摘要

PURPOSE: A method and an apparatus for testing a vibration endurance of an auto-transmission cooler of a vehicle are provided to shorten a testing time by applying vibration to a part of a frame equipped with the auto-transmission cooler. CONSTITUTION: A vibration endurance testing apparatus includes a frame assembly(11) having a structure identical to a frame assembly installed in a vehicle. An auto-transmission cooler(12) is installed at one side of the frame assembly(11). A shock absorber(14) is provided at a lower side of the frame assembly(11) in order to absorb vibration applied thereto. A pad member(15) is installed lengthwise the frame assembly(11) so as to easily transfer vibration to the frame assembly(11). A transferring member(16) is installed on the frame assembly(11) so as to transfer vibration to the frame assembly(11). A vibrator(13) is provided to apply vibration to the transferring member(16).
