The problem studied in this paper is imposed by the necessity of increasing the reliability of heat exchangers. As known, the flow in the tubular bank can cause fretting-wear and impact mechanism at the tube-support interface, which finally can result in failure of the tube. This type of failure can occur, for example, in the steam generator tubes in nuclear power plants. One of the objectives of this study is to see how some parameters such as the equivalent contact stiffness and the radial clearance, affect the interaction between the tube and the baffle-support. On the basis of numerical simulation of the impact it is possible to draw same conclusions regarding the possibilities for reduction of the contact force which is one of the main parameters in the fretting-wear.
