摘要 综述国内外在水力-机械系统特性分析中常用的基于泰勒展开的多种形式压力管道内水体的弹性模型,以及近几年研究的最新进展。针对具体算例,结合压力管道内水体的精确模型分析其他各模型的特点和应用条件。分析表明,基于变分理论和Ritz-Galerkin近似法得到的压力管道内水体的弹性模型形式易于解耦、便于应用,能够直观地描述压力管道内水体的高阶水力特性。提出有待进一步研究和分析的主要问题。 The elastic models for pipe flow of different pattems based on Taylor' s expansion commonly used in characteristic analysis of hydraulic-mechanical system at home and abroad as well as some advances in recent years were reviewed. Case study was performed to analyze the characteristic and application condition of other models based on the accurate model for water body in pressurized pipelines. The result shows that the elastic model deduced from the variation theory and Ritz-Galerkin approximation method is easy to be decoupled and widely applied, and it can give a direct description of high-order hydraulic characteristic of water body in pressurized pipelines. Finally, some main problems needed for further study were put forward.
