Description
技术领域technical field
本发明属于海洋工程技术领域，具体地，涉及一种考虑流速衰减影响的深海网衣强迫振荡试验装置。The invention belongs to the technical field of marine engineering, and in particular relates to a forced oscillation test device for deep-sea nets considering the influence of flow velocity attenuation.
背景技术Background technique
在流体力学中，Keulegan-Carpenter数(KC数)是一个无量纲数，用来描述一个在振荡流场中的物体，所受到的阻力相对惯性力之间的关系，也可可以用在一物体在静止流体中振荡的情形。KC数小表示惯性力的影响比阻力要大，KC数大表示(紊流)阻力的影响较大。In fluid mechanics, the Keulegan-Carpenter number (KC number) is a dimensionless number used to describe an object in an oscillating flow field, the relationship between the resistance and the inertial force it receives can also be used in an object Oscillating in a stationary fluid. A small KC number indicates that the influence of inertial force is greater than that of resistance, and a large KC number indicates that (turbulent flow) resistance has a greater influence.
在对深海网箱的受力研究中，由于造波机的造波能力限制，渔场网衣的实验研究仍然局限在低KC数工况下，对于网箱网衣这种细长柔性结构物，这并不能反映出网衣的真实水动力特性。In the force research on deep-sea net cages, due to the limitation of the wave-making ability of the wave generator, the experimental research on net clothing in fishing grounds is still limited to low KC number conditions. This does not reflect the true hydrodynamic properties of the net.
此外，在深海网箱结构中，前网衣会导致非常明显的流速衰减现象，从而对后网衣的动力响应影响很大；如果不考虑流速衰减影响，网箱设计偏保守，会从很大程度上增加制造成本，而当前对流速衰减的研究仍然局限在小KC数。In addition, in the deep-sea cage structure, the front net will cause a very obvious flow velocity attenuation phenomenon, which will have a great impact on the dynamic response of the rear net; However, the current research on flow rate attenuation is still limited to small KC numbers.

The first three-component force meter at the bottom can measure the force of the rear fishing net after being disturbed by the front fishing net to the incoming flow, and the second three-component force meter at the four ends of the frame prosthesis can measure the force of the front fishing net. When the stress of the fishing net interferes with the incoming flow, when the stress of the two is subtracted, it can be considered that the stress of the fishing net that goes out of the frame of the front fishing net has been measured. The application of a set of forced oscillation device designed by the present invention and the fixing device installed between the horizontal support bar and the vertical guide rail slider can effectively fix the overall frame of the fishing net and the vertical guide rail slider together, so that the fishing net can be tested with forced vibration.

This method can simulate large KC number wave conditions. The attenuation of the flow rate under the condition is more realistic to simulate the actual working conditions of the fishing ground.
