Problems solved by technology

[0003] At present, scholars at home and abroad have conducted a lot of research on the failure mechanism of marine engineering structures, but most of them are based on numerical simulation and theoretical analysis. There are very few experimental studies on the collision of marine engineering structures, and for the same jacket There may be a secondary impact phenomenon, that is, it was not discovered in time after being slightly impacted for the first time or has been discovered, but it was not repaired without affecting the continued use, and then it was impacted for the second time

Abstract

The invention discloses a clamping limiting and displacement experiment device for an impact test. The device is characterized in that a typical component node test piece is arranged on a bearing platform device, a main chord pipe and a branch pipe of the typical component node test piece are respectively connected with the bearing platform device through a sliding device, the sliding device can adjust the position of the main chord pipe on the bearing platform device according to the length of the main chord pipe, a protection device is arranged above the main chord pipe, and a drop hammer head is arranged on the protection device. According to the invention, simulation of three times of impact can be realized, replacement is convenient, and independent customization is not needed.

Description

technical field [0001] The invention belongs to the technical field of marine engineering, and in particular relates to a clamping limit and displacement experimental device for impact test. Background technique [0002] Among the existing offshore engineering structures, jacket platforms and offshore large-scale floating wind turbines are the most widely used, but at the same time, the accident rate of these two types of platforms is often the highest among all offshore platforms. According to incomplete statistics, among the capsizing incidents caused by the impact of jacket platforms and floating wind turbines every year, the impact caused by ships accounts for more than 20%, and the resulting loss of human, material and financial resources is very huge. of. Even though the field of ocean engineering has made great progress, people pay more and more attention to the safety of ocean engineering structures. [0003] At present, scholars at home and abroad have conducted a...
