In　order　to　suppress　the　low-frequency　flow-induced　vibration　of　fluid　conveying　pipeline,　this　paper　develops　a　magnetorheological　damping　(MRD)　pipe　clamp　due　to　its　simple　structure　and　strong　dynamic　adjustability.　The　mechanical　dynamic　model　of　MRD　pipe　clamp　is　established,　and　the　vibration　control　algorithm　based　on　PID　is　simulated.　Comparison　analysis　on　the　vibration　damping　performance　of　the　MRD　pipe　clamp　under　uncontrol,　passive　control,　and　PID　control　are　conducted.　The　damping　performances　of　MRD　pipe　clamp　are　tested　under　uncontrol,　passive　control,　and　PID　control　algorithm.　The　experiment　results　exhibited　that　the　attenuation　rate　of　each　axial　displacement　and　acceleration　of　pipe　system　using　PID　algorithm　were　more　than　80%　under　sinusoidal　excitation　force　of　600　N　and　excitation　frequency　of　2.5　Hz.　The　experiment　results　have　verified　the　correctness　of　the　simulation　analysis　in　terms　of　value　and　trend.　This　research　will　provide　the　guide　for　the　design　and　engineering　application　of　MRD　pipe　clamp　system.
