The present invention relates to a three-dimensional vibration tester which applies vibrations similar to actual vehicle vibrations to parts to be tested by being arranged to apply vibrations in three axis directions and to adjust vibrations according to rpm changes, thereby improving the reliability of a test and reduces costs required to introduce a vibration tester by being constructed to be mechanically driven, thereby reducing vibration test costs. The three-dimensional vibration tester according to the present invention comprises: a housing (100) including a certain internal space; multiple supporting units (200) which are installed on the top of the housing (100); a rotating shaft (300) which is installed above housing and positioned between the supporting units and in which a cam-shaped excitation member (310) is installed; a vibration plate (400) which is supported by the supporting units (200) and includes an uneven groove (410) which comes into contact with the excitation member at least at two points, on the bottom; and an driving unit (500) which is installed in the housing (100) and drives the rotating shaft (300). |
