Abstract. The article takes an approximate solution of the forced vibrations of a nonhomogeneous beam under the vibration load. It is well known that in the production of technical plates, due to the technological process and a number of other reasons, the mechanical properties depend largely on the spatial coordinates of the body points. The partial differential equation is compiled for a particular beam with a fixed cross section, then this equation is solved by an approximate method. Finally there is a relationship between forced and natural frequencies.
Keywords: Forced vibrations, homogeneous beam, vibration load, elastic modulus, forced frequency, natural frequency, Bubnov-Galerkin method.
