Abstract
A detailed three-dimensional finite element analysis model for an aero-engine compressor blade was established. Blade vibration response was experimented, considering a dry friction non-linear response method for solving for the fan blades. It can’t be calculated using the ANSYS platform when considering the dry friction situation because there is a strong nonlinear shroud contact surfaces. This article uses the trajectory tracking and time-frequency transformation method to solve the fan blades with dry friction and nonlinear response, and determine the size of the shoulder contact surface speed, pressure and contact stiffness. Then we get the frequency response of the fan blades of the state curve and the displacement, stress contours after calculating. The comparison of the results by response displacement under the condition of all the coordination with two pairs of nodes to take into account dry friction, vibration significantly reduced, but the displacement and stress distribution changed little, due to the presence of friction damping. The calculation process is quite complicated, but more precise calculations when considering dry friction damper with dry friction and nonlinear response to the solver calculation.
