An estimate of the time of a direct-axis collision of a body of finite mass and a semiinfinite cylindrical shell with fluid

The problem of a direct-axis collision of a body affinite mass and a semi-infinite cylindrical shell with fluid is considered, and is solved using an analytic-numerical method, which is based on an application of the Laplace-Carson transform with its subsequent numerical inverse. An expression is found for the interaction force for the body and the hydro-elastic system, which allows us to determine the time of collision. Numerical results of calculations of the interaction force and the time of collision are given.Translated from Dinamicheskie Sistemy, No. 7, pp. 29–32, 1988.
