Research on a New Type of Anti-vibration Supports for Hydraulic Pipelines

根据管道减振原理,设计一种新型管道液压抗振支承。该液压管道支承通过弹簧、弹簧片对振动能量进行吸收,并具有结构简单、安装方便的优点。建立振动环境下液压管道振动的数学模型,通过仿真分析安装抗振支承前后管道应力的波动响应,并进行实验验证。结果表明:该抗振支承能有效减小管道应力和流体波动,减振后管道应力最大值和流体压力平均波动幅值分别减小了14.80%、40.49%,有关结论能为在基础振动环境下的管道抗振提供一定的依据和参考。

Based on the principle of the pipeline vibration damping,a new type of damping supports is designed forpipeline’s axial and transverse vibration damping.This type of hydraulic pipeline supports has the advantages of simplestructure and easy installation.The vibration energy of the pipeline can be absorbed by the spring.The mathematical modelof the hydraulic pipeline is established for vibration analysis.Through the numerical simulation,the fluctuation responses ofthe pipeline stress before and after the installation of the anti-vibration supports are analyzed and verified by testing.Theresults show that the anti-vibration supports can effectively reduce the pipeline’s stress and fluid pressure fluctuation.Themaximum stress and the amplitude of the fluid pressure fluctuation of the pipeline are reduced by14.80%and40.49%respectively.The results of this research provide a theoretical basis for anti-vibration analysis of the pipelines on vibratingfoundations.
