Deflections of an ice cover in a frozen channel caused by a moving load are considered. The channel has a rectangular cross-section. Fluid in the channel is inviscid, incompressible and covered with ice. The ice cover is modeled as a thin elastic plate. The flow caused by the ice deflections is potential. The problem is solved within the linear theory of hydroelasticity. The load is modeled by a pressure distribution and moves along the channel at a constant speed. The load could be is of arbitrary shape and vary in calculations. The problem using the Fourier transform along the channel is reduced to the problem with respect to the deflections profile across the channel, which is solved by the method of normal modes. The solution is obtained as the sum of the integrals of the inverse Fourier transform. Strains distribution in the ice cover is studied depending on the different loads. [ABSTRACT FROM AUTHOR] |
