摘要

摘要: 针对轴向基础振动对管道和流体波动的影响,运用轴向基础振动下液压直管道轴向耦合振动数学模型,推导了4种不同管端约束方式下的边界条件,并采用特征线法对不同约束方式下基础振动诱发的管内流体波动进行了研究,分析了管端约束方式、约束刚度、基础振动参数、结构参数对管道出口压力波动幅值的影响。结果表明:与两端固定约束相比,出口轴向自由和入口轴向自由时出口流体压力波动幅值分别增大了很多,且出口处约束刚度越大,压力波动幅值越小;基础振动频率越大,流固耦合作用越剧烈;压力波动幅值随基础振动幅值增大而线性增大;流体流经管道的距离越长,流体波动越剧烈。分析结果能为制定相应的管道振动控制策略提供理论依据。

Abstract: In view of the effect of axial foundation vibration on pipe and fluid fluctuation, an axial coupling vibration mathematical model of direct hydraulic pipeline was used to deduce boundary conditions under four different pipe end constraints, and method of characteristics was adopted to study the fluid fluctuation in pipe induced by foundation vibration under different constraints. The influences of bound manner, restraint stiffness, foundation vibration parameters and structural parameters on pipe outlet pressure fluctuation amplitude were analyzed. The results indicate that the outlet pressure fluctuation amplitudes increase a lot respectively when export axial and entrance axial are free, compared with fixed constraints of both ends. And the greater the exit restraint stiffness is, the smaller the pressure fluctuation amplitude is; the higher vibration frequency is, the stronger fluid-solid interaction is; the pressure fluctuation amplitude increases linearly with the increase of foundation vibration amplitude; the longer the distance of fluid flowing through the pipe is, the severer the fluid fluctuating is. The analysis results could provide a theoretical basis for the formulation of corresponding pipe vibration control strategy.
