STUDY ON THE CHANGE OF CONTACT UNDER THE HEAVY LOAD BY OPTICAL INTERFERENCE METHOD

摘要

We are sometimes confronted with the contact problem in the plastic deformation, but it is the current state that there is no clear design technique in this sever condition. So we investigate the contact condition in the plastic deformation. As a result, we obtained the prospect of the establishment of the design technique in the plastic deformation by getting the following items. -^sThe decrease rate of the contact pressure according to an increase in the number of contact cycles did not depend on the material. -^sThe area of the minimum oil film thickness has moved into both ends of the contact area from the vicinity of a central exit as the contact region expands.
