Abstract
Hydraulic pipeline and clamp are important components of aviation hydraulic piping system. Determination of the dynamic properties of the clamp is of great significance to the analysis on the vibration characteristics of the aviation hydraulic piping system. In this study, an advanced experimental method for determining the dynamic properties of the fixed clamp of aviation hydraulic piping system was proposed. The dynamic complex stiffness of the hydraulic clamp is determined by analyzing the propagation characteristics of the bending wave of the hydraulic pipeline with clamp. Experiments were carried out using typical aluminum hydraulic pipeline and single-pipe grounded clamp specimens, and the dynamic characteristics of the hydraulic clamp were simulated using complex stiffness. The dynamic properties the hydraulic clamp were calculated by Newton-Raphson iterative method, its frequency-dependent stiffness and loss factor were derived. The proposed method allows non-destructive continuous monitoring of hydraulic clamp components in engineering practice.
