The paper discusses the development of an ultrasonic symmetric bending fatigue system on the basis of the three-point bending method,including the design of ultrasonic symmetric bending samples and the influence of processing errors.The S-N curve of 50~# axle steel is determined by the ultrasonic symmetric bending fatigue system(20 KHz).The results show that the S-N curve of 50~# axle steel is a continuously declining curve.Compared to the S-N curve of 50~# axle steel under the symmetric tension and compression loading,it is shown that in the high-cycle stage,the loading method has a significant effect on fatigue properties, and in the ultra-high-cycle stage,the loading method has no significant impact on fatigue properties.
