A New Type Fatigue Machine Design with High Frequency Large Stroke

Abstract:

The traditional fatigue machine using stepping motor as driving device has the disadvantages of low efficiency, low frequency and producing heat terribly. This paper presents the development of a new type fatigue machine using voice coil motor which has the advantage of high frequency, high accuracy and easy to control as driving device in order to make up for these deficiencies of the traditional machine. The maximum frequency of fatigue machine can reach 200Hz, and the maximum stroke will reach 30mm. The machine can test the properties of anti-fatigue crack of metal and non-metallic materials and the fatigue lives of mechanical parts. It also can provide the force curve changing with time under different frequencies when carrying on tensile and compressive test on sample, which can greatly improve the accuracy and stability of measuring system
