Objective <p>This study aims to investigate the effect of external random excitation on the dynamic characteristics of a hydraulic hose conveying fluid to improve its transfer efficiency, providing a theoretical basis for the design and selection of hoses subjected to random vibration.</p> Methods <p>The random vibration equation of motion for the hydraulic hose was first derived based on Hamilton’s principle, incorporating fluid-structure interaction (FSI). The free vibration characteristics were then analyzed using the complex mode method, considering parameters such as fluid velocity, fluid pressure, and structural properties. Subsequently, the pseudo-excitation method (PEM) was employed to solve the random vibration response under white-noise excitation. Finally, laboratory experiments were conducted to simulate the dynamic behavior of the hydraulic hose in accordance with engineering practice.</p> Results <p>The simulation results obtained from the analytical method showed good agreement with the experimental data, validating the accuracy of the proposed approach. The analysis also revealed the influence of key parameters, including fluid velocity and pressure, on the dynamic response of the hose.</p> Conclusion <p>The developed method effectively characterizes the dynamic behavior of hydraulic hoses under random excitation, demonstrating significant value for the design and optimization of hose systems in practical engineering applications.</p>
