ANSYS finite element analysis software was used to simulate and analyze the vibration characteristics of crimped straight pipe in an aeronautical hydraulic system. On the basis of obtaining the vibration characteristics of the crimped pipe, a scheme of adding an additional excitation signal to the crimped pipe interface was proposed to effectively reduce the vibration of the pipeline, and the vibration reduction effect was studied from the excitation frequency and amplitude of the excitation signal.The simulation results show that when the fundamental vibration frequency is equal to the vibration damping excitation frequency, the amplitude is the same, and the direction is opposite, the pipeline vibration damping effect is the best.
