The invention discloses a vibration test device for small parts of an automobile. According to the vibration test device for the small parts of the automobile, the structure is simple, the test process can be kept stable, integrity and trueness in the detection simulation process are high, and the obtained test result is more scientific. The vibration test device for the small parts of the automobile comprises a body, wherein two opposite fixed plates are arranged on the body, a clamping fixing base is arranged on the top of the body, each fixed plate is connected with the outer side face of the clamping fixing base through a transverse spring, a vibration-starting and speed-regulating motor is arranged on the body, a plurality of vertical springs are arranged on the lower portion of the body, at least one vertical spring is provided with a vertical vibration sensor, and at least one transverse spring is provided with a main vibration sensor. The vibration test device for the small parts of the automobile has the advantages that the structure is simple, the total weight is light, resonance in the frequency band is low, influence is low, comprehensiveness and integrity are high when detection is carried out, the simulation degree is high, and the obtained test result is more accurate and more scientific.
