“…To solve the nonlinear ordinary differential equations of motion (21) for wing vibration, the multiple-scales approach is used to obtain the system responses in time and frequency domains. In this method, an expansion representing the response to be a function of multiple independent scales is used, where is a small parameter representing the time scale [17].…”

“…Using the method of multiple scales (MMS), Zafari et al [17] presented an analytical approach to analyze the nonlinear flutter responses of a wing under a transverse follower force. MMS has also been used in the other nonlinear multi-degree of freedom systems such as nonlinear chatter vibration [18][19][20], nonlinear vibration of micro structures [21] and nonlinear vibroacoustic problems [22].…”

In this paper, the aeroelastic response of a wing containing a propeller system with rotating unbalanced mass is presented. Nonlinear structural model of the wing carrying a propeller system is extracted and coupled with an incompressible unsteady aerodynamic model. The governing equations and boundary conditions are determined via Hamilton's variational principle. Galerkin's approach is used to transfer the resulting partial differential equation into ordinary nonlinear differential equations. Using the method of multiple scales, frequency response function of the system in different primary resonance cases is obtained analytically and the flutter occurrence possibility in each case is investigated. According to the results, jump phenomenon can be observed in each two primary resonance cases. Also, for the case of non-resonant excitation, the stability of the system is independent of the rotating unbalanced mass parameter.

“…The differences are explained by the authors with decreasing damping at high speeds and the Coriolis-effect due to rotational and vibrational movements. Mokhtari et al [144] presented a novel method to study the unstable vibrational behaviour of micro-milling. Their studies took into account the size effect, the gyroscopic moment, the rotary inertia, the structural nonlinearities and process damping.…”

Recently, mechanical micro-milling is one of the most promising micro-manufacturing processes for productive and accurate complex-feature generation in various materials including metals, ceramics, polymers and composites. The micro-milling technology is widely adapted already in many high-tech industrial sectors; however, its reliability and predictability require further developments. In this paper, micro-milling related recent results and developments are reviewed and discussed including micro-chip removal and micro-burr formation mechanisms, cutting forces, cutting temperature, vibrations, surface roughness, cutting fluids, workpiece materials, process monitoring, micro-tools and coatings, and process-modelling. Finally, possible future trends and research directions are highlighted in the micro-milling and micro-machining areas.
