Based on the solution of the problem of scattering of a plane harmonic wave by a rigid spherical body within a semi-infinite cylindrical cavity filled with a fluid, we have determined the radiation force acting on the body as a function of the primary wave frequency and the physical and geometrical parameters of the mechanical system. The total wave field potential has been expressed in a computationally convenient form. The numerical simulations have shown that the end wall of the cylindrical cavity significantly affects the radiation force acting on the spherical body at frequencies exceeding the first natural frequency of the radial oscillations of the fluid in the cylindrical cavity. As the gap between the boundaries of the body and the cavity decreases, at frequencies of the incident wave close to the "resonant" ones for the studied mechanical system, the radiation force increases significantly. The described methodology enables precise calculation of the radiation force and facilitates the determination of the incident wave frequency required for controlled motion and localization of a spherical body within a cylindrical cavity.
