To get fatigue properties of the small and hard brittle components working at conditions of little amplitudes and high frequency forces, this paper presents a novel kind of resonance and high frequency fatigue testing machine driven by a piezoelectric vibrator (PZT、PLZT or PMN). First, the working principle of the piezoelectric resonance and high frequency fatigue testing machine was introduced, and the dynamic model of the machine was established and its systemic dynamic characteristics were obtained. Then, a prototype was designed and produced. Finally, the dynamic load on the specimen was measured by the prototype. The results indicate that the dynamic load on the specimen is 24.7-99.2 N by changing the AC voltage amplitude (100-250 V) and the thickness of the plate spring (1.1-0.6 mm). The prototype designed in this paper is suitable for the tensile and bending fatigue testing under conditions of little amplitudes and high frequency forces with the dynamic load mentioned above.
