Modal analysis of two typical fluid-filled pipes in aircraft
The vibration of hydraulic pipe poses a severe safety concern in aircraft. Aiming at this problem, the two typical pipelines (straight pipe and curved pipe) were analyzed using the Finite Element Method (FEM) in ADINA software. Compared with the experiment, the results from ADINA simulation are close to the experiment data. Based on the simulation results, we concluded that adjusting the clamped-end length or consolidating the pipe are effective ways to change the natural frequencies of fluid-filled pipe and prevent the drastic vibration of the pipeline system in aircraft when the natural frequencies of the fluid-filled pipe fall into the frequency range of vibration source.
