RESULTS OF SOLVING THE EQUATIONS DESCRIBING IMPACT AGAINST THE BOTTOM PLATE OF A HIGH-SPEED SHIP

This article contains an investigation of impact of a rectangular plate freely supported along the outline and attached in one direction by equally spaced ribs against the surface of a liquid. It is considered that contact takes place simultaneously along the entire surface and the impact load is uniformly distributed. The pressure variation with time during the impact is taken on the basis of experimental research. Being given the form of the deflection of the plate W (symmetrical deformation) a system of two ordinary nonlinear second order differential equations with respect to generalized coordinates is obtained by means of the Lagrange equations of the second type. In further calculations the nonlinear terms considering the effect of the longitudinal forces are dropped. The solution of the system is found numerically on a digital computer. The effect of the build-up time of the external pressure and the rib rigidity on the amplitude of the plate oscillations was studied. terms considering the effect of the longitudinal forces are dropped.
