Abstract

The invention provides an experimental device for flow-induced vibration of a tube bundle. The experimental device for flow-induced vibration of the tube bundle comprises a shell-shaped flow-induced vibration experimental device. The tube bundle supported by a supporting plate is arranged in the flow-induced vibration experimental device. The two ends of the flow-induced vibration experimental device are flanges. An acceleration sensor is arranged in the flow-induced vibration experimental device. The upper portion of the flow-induced vibration experimental device is connected with a water pump through a pipeline which is provided with a pressure gauge, a flow meter and a first valve in sequence. The water pump is further connected with a water tank through a pipeline provided with a second valve. The water tank is connected with the bottom of the flow-induced vibration experimental device through a pipeline provided with a third valve. The portion, between the water tank and the third valve, of the pipeline and the portion, between the flow meter and the first valve, of the pipeline are connected with each other through a pipeline provided with a fourth valve. The experimental device for flow-induced vibration of the tube bundle is really effective.

Description

technical field [0001] The invention relates to the technical field of a flow-induced tube bundle vibration dynamics analysis device, in particular to a flow-induced tube bundle vibration experiment device. Background technique [0002] Catastrophic accidents caused by the vibration of the tube bundle caused by the fluid happen from time to time. In industries such as offshore platforms, nuclear power plants, and petroleum and petrochemical industries, under the action of fluids, marine well group risers and heat exchanger tube bundles may induce excessive vibration of the tube bundles, causing collisions between the tube bundles, resulting in failure of the tube bundles. From the 1960s to the present, flow-induced tube bundle vibration dynamics analysis has been one of the most active basic research fields in tube bundle design. The purpose of this experimental device design is to simulate the occurrence process of flow-induced tube bundle vibration, detect and analyze the...
