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 limit and displacement experimental device for impact test. A typical component node test piece is set on a platform device, and the main chord and branch pipes of the typical component node test component pass through the sliding device and the platform device respectively. connection, the sliding device can adjust its position on the platform device according to the length of the main chord, a protective device is arranged above the main chord, and a drop hammer is arranged on the protective device. The present invention can realize the simulation of three impacts; it is convenient to replace and does not need to be individually customized.

Description

technical field [0001] The invention belongs to the technical field of marine engineering, and particularly relates to a clamping limit and displacement experimental device for impact testing. Background technique [0002] Among the existing offshore engineering structures, jacket platforms and large offshore floating wind turbines are the most widely used, but at the same time, the accident rates of these two types of platforms are often the highest among all offshore platforms. According to incomplete statistics, among the overturning events caused by the impact of jacket platforms and floating wind turbines every year, the impact of ships accounts for more than 20%, and the loss of human, material and financial resources is huge. of. Even under the circumstance that the field of marine engineering has made great progress, people pay more and more attention to the safety of marine engineering structures. [0003] At present, scholars at home and abroad have carried out a...
