A hydraulic pipe is Papar a basic component of the aero hydraulic system, while high pressure and high speed lead to the enhancement of multiple field coupling effects, such as the structure, fluid, heat, and sound of the aero hydraulic pipe.A larger elastic deformation of the pipe and the more common unsteady flow of fluid can aggravate the vibrat
