Nonlinear stress analysis of aero-engine pipeline based on semi-analytical method

Applied Mathematics and Mechanics(English Edition) 2025年第3期46卷 521-538页

作者： Weijiao CHEN Xiaochi QU Ruixin ZHANG Xumin GUO Hui MA Bangchun WEN School of Mechanical Engineering and Automation Northeastern University Key Laboratory of Vibration and Control of Aero-Propulsion Systems Ministry of Education of china Northeastern University

Fatigue failure caused by vibration is the most common type of pipeline failure. The core of this research is to obtain the nonlinear dynamic stress of a pipeline system accurately and efficiently, a topic that needs to be explored in the existing literature. The shell theory can better simulate the circumferential stress distribution, and thus the Mindlin-Reissner shell theory is used to model the pipeline. In this paper, the continuous pipeline system is combined with clamps through modal expansion for the first time,which realizes the coupling problem between a shell and a clamp. While the Bouc-Wen model is used to simulate the nonlinear external force generated by a clamp, the nonlinear coupling characteristics of the system are effectively captured. Then, the dynamic equation of the clamp-pipeline system is established according to the Lagrange energy equation. Based on the resonance frequency and stress amplitude obtained from the experiment, the nonlinear parameters of the clamp are identified with the semi-analytical method(SAM) and particle swarm optimization(PSO) algorithm. This study provides a theoretical basis for the clamp-pipeline system and an efficient and universal solution for stress prediction and analysis of pipelines in engineering.
