Measurement Method in Model Test of Ice Breaking by Air Cushion Vehicle

Abstract:

A high accuracy non-contact laser displacement measuring system is developed to obtain the surface deformation of the ice-like material. A speed measurement and positioning system is established for the moving air cushion load. The mechanical properties of the ice-like material and the pressure distribution of air cushion load are measured. Under different air cushion load and different speed, a series of experiments of the deformation of ice-like material are carried out in towing channel which the depth of water is variable. The maximum deformation of ice-like material can be caused when air cushion load moves at critical speed, and the ice-water resonance mechanism of ice-breaking by air cushion is revealed, which provides the basis of ice-breaking for practical air cushion vehicle.
