The high frequency electrohydraulic vibration system is applied widely in engineering technology field，especially it occupied important position in the test of reliability and durability of auto parts. The application of the high frequency electrohydraulic vibration system in auto parts test was introduced emphatically. And composition, control principle, control optimization of the high frequency vibration system were introduced. Application results show that the vibration force achieves to 10 kN, the vibration frequency achieves to 120 Hz, the precision is ±005 mm or ±50 N, and it satisfies actual used requirements of highfrequency, highprecision and highstability.
