充液管路流固耦合振动研究进展

Research Progress of Fluid-solid Coupling Vibration of Liquid-filled Pipes

根据充液直管和弯管管路在空间放置和运动形式分为固定水平放置、固定空间某一位姿放置和空间运动等几种类型.针对充液管道线性、非线性流固耦合振动模型及其振动分析方法,总结归纳文献[1-2]综述之后学者的相关研究成果,梳理当前的研究进展,提炼今后的发展方向.目前对固定水平放置的直管和弯管的耦合振动模型及其分析方法已趋成熟,对固定某一位姿的直管和弯管也得到了较为充分的研究.对在支承条件下受外界周期激励时的管路振动模型及其分析方法研究成为了研究热点.对管路随被支撑系统的复杂空间运动的振动模型及其分析方法研究极少,这类管路将具有更丰富更复杂的振动行为,尤其值得更深入的研究.

The research on and the development of the liquid-filled piping system,fluid-solid coupling vibration model and vibration analysis methods are summarized.The spatial placement and motion form of liquid-filled straight pipes and elbows is divided into the fixed horizontal placement,spatial placement of a particular fixed posture and spatial motion,etc.Related research achievements related to the liquidfilled pipeline ’linear and nonlinear fluid-solid coupling vibration model and vibration analysis methods are summarized,and the direction of future development is proposed.The current coupling vibration model of the straight pipes and elbows of fixed horizontal placement and its analysis methods have been basically mature,and those for the straight pipes and elbows of a particular fixed posture have also been thoroughly studied.The pipeline vibration model subject to external periodic excitation under the support conditions and its analysis methods have become the focus.The vibration model for the complex spatial motion of pipes with the supported system and its analysis methods are seldom studied.Because such pipes have more abundant and complex vibration behaviors,they are worth further study.
