“…Mechanical vibrations are common in various types of hydraulic systems. Feng Gao [9] selected the specific benchmark of NiCoCrAlY + YSZ hard coating deposited on the detuned blisk for numerical calculation, and studied the vibration reduction characteristics of the detuned blisk with a hard coating. Cross [10] and Patsias S [11] applied ceramic coatings to the surface of engine blades, analyzing and comparing the damping characteristics of the blades before and after coating.…”

Aviation hydraulic clamp-piping systems often experience damage due to vibration, which poses a great threat to the reliability and safety of the aircraft. In this paper, a hard coating is used as a new damping method to study the vibration characteristics of aviation hydraulic clamp-piping systems. Three kinds of coated clamp entities are obtained by optimization and preparation, and the combination of finite element simulation and experiment is used to analyze the vibration response of the high- and low-pressure rotor under fixed-frequency simple harmonic excitation, and the resonance response under sweep-frequency excitation of the aviation hydraulic clamp-piping system. Through orthogonal experiments, it is clear that 304 stainless steel clamps coated with 200-μm-thick YSZ-PTFE coating have the best vibration damping effect on the clamp-piping system; that is, the damping rate can reach 24.67% under fixed-frequency excitation, and swept frequency damping can reach 19.93%. The maximum error between the simulation and the experimental vibration response amplitude is 7.9%, which proves the correctness of the model and verifies that the YSZ-PTFE hard coating can significantly improve the vibration damping effect with very good application prospects.

To improve the performance and reduce the vibration of the mistuned blisk, a novel approach combining the hard-coating and multi-packets is presented. Firstly, the dynamical models of the blisk without hard-coating and multi-packets, the hard-coated mistuned blisk without multi-packets, and the hard-coated mistuned blisk with multi-packets, are established based on the lumped parameter model (LPM). Then, the solved results are compared with that of previous literature to validate the feasibility and correctness of the proposed models. Furthermore, the characteristics of the natural frequencies and the vibration responses for the mistuned blisk are investigated by proposed LPMs. Finally, the effect of the hard-coating and multi-packets on the vibration characteristics for the mistuned blisk are discussed. The obtained results manifest that the vibration response of the mistuned blisk can be further suppressed when the hard-coating and the multi-packets are considered simultaneously compared with only the hard-coating or multi-packets considered, which provides useful guidance on the vibration reduction for the mistuned blisk.
