Abstract

The invention relates to a three-phase coupling capsule type floating bridge wave resistance impact performance detection method and system. The method is characterized by extracting a bearing plate,a capsule body, a skirt geometric parameter and an axial spatial geometric parameter according to a capsule type floating bridge design drawing; extracting a material parameter according to the actualmaterial of a capsule type floating bridge; according to hydrological information, providing an environment parameter; and using the material, an environment and a design dimension parameter to establish a full three-dimensional capsule type floating bridge model, using a penalty function mode to realize fluid-solid coupling and structure contact, combining floating bridge static load test data to check a calculation parameter, and using a numerical wave generation technology to carry out the safety detection of floating bridge wave resistance impact. In the invention, a wave resistance impact performance detection problem during a capsule type floating bridge design process is solved, the method is simple and is easy to operate, the understanding of a capsule type floating bridge structure stress distribution condition is deepened, facility design efficiency is effectively improved, and the randomness of a test and a fund investment are reduced.

Description

technical field [0001] The invention relates to the technical field of detection and measurement, in particular to a method and system for detecting the anti-wave shock performance of a three-phase coupled capsule floating bridge. Background technique [0002] The new bladder type pontoon is a new type of pontoon developed by the U.S. Navy in 2008. The new type of pontoon uses air filling as a floating body. Due to its greatly reduced self-weight, a large displacement will occur when the wave hits, which will affect the traffic capacity of the pontoon bridge. If its structural design research is completed through physical tests, the design cost will be very high. Therefore, there is an urgent need for a set of testing methods for the anti-wave impact performance of three-phase coupled bladder pontoons, which can guide the structural design of bladder pontoons and reduce test costs. [0003] After searching the existing methods, it is found that in addition to using physica...
