Based on acoustic scattering theory, the analytical expression of acoustic radiation force acting on a visco-elastic coated sphere located in an infinite rigid cylindrical cavity filled with ideal fluid is deduced for a plane progressive wave. The effects of the cylindrical cavity, the material of the sphere and the coated thicknesses on acoustic radiation force are discussed. The simulation results show that the cavity has influence on the values and directions of acoustic radiation force. The fluctuation of the acoustic radiation force curves is obvious with the increase of the spherical relative radius. The resonant modes and the magnitude of the acoustic radiation force are affected by the coated material. The forces appear different resonance peaks because of the difference of the coating materials. The resonant modes of the acoustic radiation forces on the sphere are changed with the variation of the core material. In addition, the resonant positions shift to higher frequencies when the coated thickness of the sphere becomes thinner. More resonant modes appear under this condition.
