“…The effects of external excitation, fluid velocity, fluid pressure, and structural parameters on the stress of a composite pipe were also studied. (9) Xu et al established a finite element model of tubing corrosion based on the corrosion mode, fluid-structure coupling, and the influence of sand to clarify the relationship between the tubing corrosion law and failure areas. (1) Duan et al simulated and analyzed modal changes of dry and wet single pipelines and discussed the influence of the fluid-solid coupling effect, inlet pressure, and ambient temperature on the tubing.…”

Under the excitation of hydraulic oil, fluid-structure coupling affects a hydraulic hose. We analyzed the vibration characteristics and optimized the parameters of the vibration of a hydraulic hose. SolidWorks was used to model a three-layer steel wire wound around a polytetrafluoroethylene (PTFE) hose. A two-way fluid-structure coupling model was built to analyze the influence of different parameters on the displacement by vibration and the fluid vibration speed. A three-factor and three-level Taguchi experiment with displacement was carried out to verify the influence of the parameters. In the analysis of the response surface, fitting regression was conducted using the Box-Behnken method to analyze the vibration displacement. The optimal predicted parameters were a winding angle of 53.8384°, a wall thickness of 7.31313 mm, and a bending radius of 164.343 mm. The error between the predicted and simulated values was ±3.5% for the optimized parameters and the displacement was reduced by 47% for the optimal parameters. The optimal parameters can be used as reference values to improve the working life of vibrating hydraulic hoses in future studies on the vibration characteristics of hydraulic hose systems.

“…For example, Zhai et al (2011) established the equation of motion of the pipeline conveying fluid based on the finite element method and used the pseudo excitation and the complex mode superposition theories to solve the equation. Qu et al (2021) used Hamilton’s principle to establish the hydraulic composite pipeline motion equation and used the random vibration discrete analysis method to solve the vibration behaviors of pipeline systems under white noise excitation. Sazesh and Shams (2019) used the Galerkin method to discretize the motion equation of the cantilever pipeline and then analyzed the vibration response with white noise excitation as the random load.…”

Purpose In many cases, the external pipelines of aero-engine are subjected to random excitation. The purpose of this paper is to reduce the vibration response of the pipeline system effectively by adjusting the hoop layout. Design/methodology/approach In this paper, a spatial pipeline supported by multi-hoops is taken as the object, the methods of solution of the vibration response of the pipeline system by using pseudo excitation and hoop layouts optimization with amplitude reduction of vibration response as the goal are presented. First, the finite element model of the spatial pipeline system is presented. Then, an optimization model spatial pipeline is established. Finally, a case study is carried out to prove the rationality of the random vibration response analysis of the pipeline system. Furthermore, the proposed optimization model and genetic algorithm are applied to optimize the hoop layout. Findings The results show that the maximum response variance after optimization is reduced by 32.8%, which proves the rationality of the developed hoop layout optimization method. Originality/value The pseudo excitation method is used to solve the vibration response of aero-engine pipeline system, and the optimization of the hoop layout for aero-engine spatial pipelines under random excitation to reduce random vibration response is studied systematically.
