Sink.
Background technique
It is tied with the development of Marine Sciences and the progress of defense technology, Ship Structure impact resistance and under wave environment
Attention of the fatigue strength of structure increasingly by various countries' exploitation to ocean engineering research.And with the high speed development of social economy, ocean
The development and research of resource has become the main strategic target of multinational development, therefore rule and ship knot to marine motor
The research of kinetic characteristic of the structure under different waters, and it is increasingly heavy to the research of marine structure and seashore infrastructure
It wants.
Ship Structure impact resistance test and the test of structural fatigue strength and stability under calm water surface have obtained
The abundant research of domestic and foreign scholars, but the working condition tests under different waters wave environment are not studied sufficiently yet, mainly because
In different waters wave patterns multiplicity and to simulate that wave environment is more demanding to test site, realize the wave of high quality compared with
For difficulty.
Currently, being roughly divided into three kinds to the test method under different wave environments both at home and abroad, first method is to expand examination
Place is tested, test site is larger, and active wave simulator produces ideal wave, and since test site size is larger, wave is being moved
In transmittance process, energy is consumed, and passive wave absorption region is arranged at test site edge, eliminates the reflection of wave, should
Method limitation is larger, and required test site is larger, somewhat expensive and precision is not high.Second method makes unrestrained sink to be small-sized,
The sink unidirectionally makes wave, installs small-sized passive wave-absorbing bank making the unrestrained water tank device other side, this method to wave eliminate ability compared with
Difference, can not eliminate back wave in real time, and test wave is of poor quality.The third method is that Active Compensation makes unrestrained sink, is making unrestrained sink
Wave is actively made in side, and unrestrained height measuring instrument is arranged before sink makes unrestrained device, and the waverecord that boundary is reflected back is fed back to actively
Unrestrained system is made, system is according to the wave information Active Compensation wave size fed back to, under the premise of keeping target wave constant, actively
The wave being reflected back is eliminated, this method realization is more difficult, and can not accomplish the high-precision and high quality of target wave.
