Abstract

The invention discloses a wave simulation generating device under a high gravity field. The adoption of a wave absorbing unit can enhance the wave absorbing effect, reduce the influence of a reflectedwave on a waveform, and ensure the similarity of a wave simulation experiment to real environment simulation. The wave absorbing unit can adjust the position of a wave absorbing plate and the size ofa grating opening according to the waveform generated by a wave generating unit so as to ensure an optimal wave absorbing effect. The wave generating unit realizes force transfer and the decoupling of motion in a simple structure. Compared with a transmission structure with a long transmission path and a complicated structure, the wave simulation generating device is less affected by mechanism jamming caused by deformation of a centrifugal field and ensures the rigidity and stability of a transmission mechanism more easily. Different from a conventional way of moving a push plate as a whole,only the upper part of the push plate is pushed, and so the load on the push plate is small and required power is small. The wave simulation generating device under a high gravity field is suitable for simulation of waves with high water depth and large amplitude.
