A Simple Round Tube Throwing Device

Abstract

The invention discloses a simple round pipe flailing device, which comprises a driving pipe, a driven pipe, a supporting device, a loading device and measuring devices, wherein one end of the driving pipe is connected with the supporting device, the other end of the driving pipe is connected with the loading device, the two ends of the driven pipe are fixed through the supporting device, and is in orthogonality with the driving pipe, and the measuring devices are arranged at the two sides of the driving pipe and the driven pipe. The simple round pipe flailing device has the advantages that one end of a driving rod is lifted through a motor, the driving rod is released through a fast unlocking device, under the effect of a spring device, the driving rod flails to collide with the driven pipe in orthogonality with the driving rod, the goal of colliding with the round pipe through the flailing of the round pipe can be realized, and in addition, relevant data is recorded through a test system. The simple round pipe flailing device has the advantages that experiment conditions are provided for the collision dynamic response of the two pipes, so that the influence of the pipeline flailing on other pipelines can be evaluated.

Description

technical field [0001] The invention relates to a simple circular tube swinging device, in particular to a dynamic test device for swinging and impacting a circular tube, and belongs to the field of dynamic experiment devices. Background technique [0002] In important industrial sectors such as nuclear power plants, petrochemicals, gas and civil construction, the pressure pipe network that transports a large amount of high-energy (high temperature, high pressure) liquids and gases constitutes the artery of these industrial sectors. Due to accidents, objects or fragments produced after the explosion hit the round pipe, which will cause local rupture and penetration, resulting in the leakage of a large amount of harmful liquid or gas, forming environmental pollution and even explosion and fire, resulting in huge losses of life and property. . In addition, once the pipeline ruptures, the jetted high-pressure fluid will generate a huge reaction force, and cause the pipeline to...

Problems solved by technology

[0003] Some progress has been made in the research on the plastic dynamic response of circular tube swinging, but there are still many issues to be explored, such as the development of local depression and its influence when the circular tube is swinging, etc.

As for the impact of the swinging circular tube and the circular tube structure and its impact with other structures and equipment, only one related experiment and simple analysis report have been found so far.

Although some simplified analyzes are available for this problem, the collision between two deformable bodies will bring more coupling effects, making the analysis more complicated and some special phenomena may appear
