Model Experiment of Ice Breaking by Moving Air Cushion Load

Abstract:

According to the differential equation of thin elastic vibrating plate and the similarity theory, the similar relationships of corresponding parameters between model and prototype as well as between the ice-like material and the real ice are established. 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. At different moving speed of air cushion load, a series of experiments of the deformation of ice-like material are carried out in towing channel which the depth of water is variable. At critical speed the maximum deformation of ice-like material can be caused, and the theory is derived and analyzed. Research results present the basis of ice-breaking for practical air cushion vehicle (ACV).
