Vibrations in aircraft hydraulic pipeline system, due to multi-source excitation of high fluid
pressure fluctuation and serious vibration environment of airframe, can cause the pipeline …

Aiming to attenuate low-frequency wave in pipes, a novel metamaterial pipe with attached
compliant quasi-zero-stiffness (QZS) resonators is proposed. The compliant resonator with …

The operation of mechanical systems generates vibrations with a certain range of
frequencies. Pipes conveying fluid have multiple natural frequencies. It is difficult to avoid …

Fatigue failure caused by high pressure of fluid and external vibration seriously affects the
performance and reliability of hydraulic pipelines. Probabilistic fatigue life assessment can …

This paper proposes a response spectrum method to assess the fatigue damage of aero-
hydraulic pipeline systems subjected to random airframe motion. A real-valued analytical …

In this paper, a design strategy to keep a pipe away from resonance by adjusting retaining
clips is presented. The pipe natural frequency is within the band of vibration frequencies …

Aero hydraulic pipeline systems are subjected to internal fluid fluctuations and random base
motions during operation, resulting in time-varying system parameters and nonstationary …

Pipes are usually constrained by multiple distributed retaining clips (MRCs). In addition,
pi** fluids are always required for higher velocities. In this paper, the effect of MRCs …

Accurate identification of faults in the aero-engine hydraulic pipelines is of great significance
for condition monitoring of engines as well as safe and reliable operation of aircraft …

Pipeline systems in aircraft are connected to the airframe through numerous clamps. There
are multiple excitation points and the excitation frequency range is wide, being influenced by …
