【Abstract】 Aero-engine pipeline systems are critical auxiliary structures that can affect engine service performance and reliability. Due to complex spatial configurations and multi-component coupling, excessive vibration and fatigue failure are easily induced under multi-source excitations and multi-physical-field interactions. Therefore, accurate and efficient dynamic models are required. Optimization design and vibration suppression should also be considered to improve the service performance of pipeline systems. In this study, the mechanical modeling methods of support components are first reviewed. Then, the principles, characteristics, applicability, and theoretical differences of semi-analytical methods, transfer matrix methods, finite element methods, spectral element methods, absolute nodal coordinate formulations, and hybrid modeling methods are summarized. The research progress in dynamic optimization design is discussed from two aspects: clamp layout optimization and pipeline routing optimization. Vibration suppression methods are further reviewed from three technical routes: support-structure-based vibration isolation, additional damping and energy dissipation, and source-side fluid pulsation attenuation. Finally, key scientific issues and future technical directions are discussed. This review is expected to provide theoretical guidance and technical support for dynamic modeling and low-vibration design of aero-engine pipeline systems.更多还原
