Slipping behavior and deformation of a disk/blade dovetail assembly are analysed using a finite element method and a program is developed for these contact problems. To analyse with high accuracy it is necessary to use an exact frictional coefficient. This frictional coefficient is obtained through a complex loading test and includes any changes in the frictional coefficient occurring during cyclic loading. The blade damping capacity of this disk/blade dovetail assembly which is calculated from the calculated results of slipping behavior, and these results coincide well with those of other experimental results. The fretting fatigue strength is also estimated based on the calculated results of stress distribution on the contact surface. Finally, these calculated results are confirmed by the measurment of dovetail slot stresses under actual operating loading conditions.
