Experimental device for studying slamming load and pressure distribution of broken waves on cylinder

Abstract

The invention discloses an experimental device for studying slamming load and pressure distribution of broken waves on a cylinder. The experimental device comprises an experimental water tank, a slope model arranged at the bottom of the experimental water tank, a guide rail arranged on the experimental water tank and a cylinder structure model arranged on the guide rail. The cylindrical structure model can slide along the guide rail of the experimental water tank, so that the relative position of the cylindrical structure and a wave breaking point is changed under the condition that the slope model is not moved. According to the experimental device, the process that waves spread along different gradients and then are broken can be achieved, and if the incident wave spreading gradient needs to be changed, only the total length of the head wave direction aluminum alloy profile and the total length of steel plates laid on the aluminum alloy profile need to be adjusted; according to the experimental device, wave slamming loads at different positions under the same wave condition can be measured, and only the position of the sliding block needs to be adjusted; the experimental device can measure the distribution of wave slamming pressure along the surface of the cylinder, and only a pressure sensor needs to be installed on a pre-reserved bolt hole.

Description

technical field [0001] The invention relates to a novel experimental device for researching crushing wave slamming load, in particular to an experimental device for studying the propagation characteristics of waves on different slopes, the stress of cylinders at different positions and the law of pressure distribution. Background technique [0002] At present, the traditional research on breaking wave slamming of offshore structures mainly includes theoretical research, numerical simulation research and physical model experiment research. Due to the complexity of the wave breaking process, the corresponding theoretical research is less, and it is difficult to apply to practical engineering; while the numerical simulation process of the breaking wave requires a huge amount of calculation, and at the same time, the aeration phenomenon when the breaking wave interacts with the cylindrical structure is relatively complex. Obviously, the accuracy and precision of numerical simula...
