TRANSIENT VIBRATION IN PIPELINE SYSTEMS

虽然瞬态振动对管道系统安全的威胁已被广泛认识，但对瞬态波传播的耦合特性却没有明确的认识，也没有准确的分析工具。本项目旨在发展有效的分析和实验方法，研究管道接头和弯道处不同类型的瞬态波之间的相互作用，并通过实验表征瞬态激励。从该项目中获得的理解和技术有望为石油、化工和炼油行业复杂管道系统的安全设计提供可靠的工具。

Although the threat of transient vibration to the safety of pipeline systems has been widely recognised, neither the coupling characteristics in transient wave propagation are clearly understood, nor accurate tools are available for analysing them. The aims of this project are to develop effective analytical and experimental methods, to study the interactions between transient waves of different types at pipe joints and bends, and to experimentally characterise the transient excitations. The understanding and techniques developed from this project hold promise in providing reliable tools for safe design of complex pipeline systems in petroleum, chemical and refinery industries.
