Abstract: In this paper, in order to study the vibration characteristics of wet friction plates commonly used with three different kinds of oil groove structures, three-dimensional finite element models were established for no groove wet friction plate, radial groove wet friction plate and the spiral groove wet friction plate. The free modal analyses of the friction plates with three different kinds of oil groove structures are carried out by using the ANSYS Workbench software. The seventh-order to twelfth-order vibration modes are obtained. At the same time, the modal analyses show that the natural frequencies of the non-groove friction plate are larger than the natural frequencies of the other two kinds of friction plates, and the natural frequencies of the radial groove friction plate and the spiral groove friction plate is changed with the change of the number of the oil groove.

Keywords: wet friction plate; oil groove structure; finite element method; free modal analysis.
