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...
