Abstract

PURPOSE: To obtain a fretting fatigue test equipment for a structure having surface contact through fitting, for example, in which the slip can be controlled arbitrarily. CONSTITUTION: An actuator 10 applies a stress to a test piece 1 which is subjected to a pushing force from a rod 4 with one end being held by means of springs 1, 2 disposed in a base 9. A pushing piece 2 is fixed to a pushing piece adjusting metal 3 fixed to the forward end of a pushing leaf spring 11 of the base 9. Furthermore, the pushing piece adjusting metal 3 is fixed such that it can be adjusted finely in the vertical and horizontal directions in an adjusting groove 12 by means of the pushing leaf spring 11. Consequently, a slip can be set arbitrarily by adjusting the position of a nut 5 and a washer 6 depending on the stress and varying the spring constant of a combination spring 1, 2.

2. Description of the Related Art Generally, when members having different rigidity are brought into contact with each other with a certain surface pressure by fitting connection such as shrink fitting, bolt connection, key connection or the like to form an integrated structure, it is not a completely integrated structure. When an external force repeatedly acts on the contact part, a small relative slip occurs along with the repeated stress at the contact part. This minute relative slip makes the contact surface rough and promotes fatigue damage caused by repeated stress due to the accompanying surface shearing force, resulting in so-called fretting fatigue. Therefore, in order to evaluate the fretting fatigue correctly, it is necessary to control the relative slip in performing the fretting fatigue test.
