ABSTRACT In the paper, the development in the manufacture of rotating bending fatigue machine is outlined, and the necessity for china to design and manufacture the rotating bending fatigue machine which is high quality and high efficiency is discussed . The design process and the performance of the 4-axises rotating bending machine made by the author is mainly presented in this paper. This machine is used for the column fatigue test specimens. It can work with four fatigue test specimens at one time .It is special because of its directly show of the number of fatigue cycles and self-stop device .it also operates conveniently and reliably. In this paper,the author will describe not only the design process of the principal axis、the clamp and the method to load ,but also the check of strength、the choice of the tolerance。In the end,it offers a assembly drawing ,which provides a way to know the fatigue machine more。 Key words : fatigue machine; design process ; the check of strength; tolerance; assembly drawing。
