Abstract

Friction dampers are widely used to improve the performance of rotating blades. This paper is concerned with the steady stale response and stability analysis of rotating composite plates in the presence of non linear friction damping. Direct Integration Method (DIM) and Harmonic Balance Method (IIBM) are used to determine the steady stale response due to periodic lateral external forces. In addition, an alternate procedure, Hybrid Method (IIM) is proposed for this analysis to substantiate the results from DIM and IIBM. The analysis shows that the steady stale response is a function of friction damping magnitude as well as its location besides the excitation frequency and the rotational speed. A stability analysis of the composite blades is also made by including periodic in-plane excitation using Floquel-Liapunov theory.
