Abstract

The invention discloses a magneto-rheological pipeline vibration mitigation system and a vibration mitigation method. The magneto-rheological pipeline vibration mitigation system comprises vibration sensors, a vibration mitigation mechanism and a controller, wherein the vibration sensors are arranged at the front end of a position, needing vibration mitigation, of the pipeline and are uniformly and fixedly arranged along the circumferential direction of the pipeline, the vibration mitigation mechanism comprises a shaft sleeve which is fixedly arranged on the outer periphery of a position, needing vibration mitigation, of the pipeline in a sleeve mode and magneto-rheological dampers which are fixedly connected between the shaft sleeve and the pipeline in a distributed manner along the circumferential direction of the pipeline, and the controller is connected with the vibration sensors and the magneto-rheological dampers, and is used for receiving the vibration quantity detected by eachvibration sensor in real time, adjusting a control current of the magneto-rheological damper at the corresponding position according to the vibration quantity, and then adjusting damping force of magneto-rheological fluid in the magneto-rheological dampers. According to the vibration mitigation system and vibration mitigation method, the vibration quantity to be transmitted can be obtained, an anti-vibration response can be made in advance, and finally the effects of mitigating vibration according to needs and mitigating vibration according to the quantity are achieved.

Description

technical field [0001] The invention relates to the field of pipeline vibration reduction, and in particular provides a magneto-rheological pipeline vibration reduction system and a vibration reduction method. Background technique [0002] Pipeline vibration is a common phenomenon. Severe vibration will cause fatigue damage to the pipeline structure and pipeline accessories, especially the loosening and rupture of the connection parts of the pipeline, which may cause leakage in light cases, and explosion and combustion in severe cases, resulting in serious damage, and even cause secondary disasters, so vibration isolation is of great significance to pipelines. [0003] The existing pipeline vibration reduction methods mainly use passive damping elements or devices such as vibration isolation devices and passive hydraulic systems to consume vibration energy and achieve vibration suppression effects. However, this passive vibration reduction method has great limitations. It c...
