Abstract The impact of solid bodies occurs in machines and it is the primary reason of noise and vibration. To understand the quantitative characteristics of noise and vibration, it is necessary to understand the motion of solid bodies, especially the deformation of the surface. In this study the authors analyze theoretically and numerically the impact phenomena on a falling body of a Timoshenko beam. Also we have compared a Bernoulli-Euler hinged-hinged beam and a Timoshenko hinged-hinged beam with regard to the impact of a cylindrical body on each of them. The conclusions are as follows: (1) the impact force, the deflection and the bending moment of the Timoshenko beam, and the displacement of the falling body can be calculated precisely according to the equations derived from this study, (2) the examination of the Timoshenko beam are compared with that of the Bernoulli-Euler beam, (3) the Timoshenko beam deflections with the passage of time are illustrated.
