摘要：

It is proposed to solve problems on natural vibrations of rectangular plates of variable thickness under complex boundary conditions using the numerical-analytical spline-collocation method in combination with the discrete-orthogonalization method and the experimental method of holographic interferometry. As a mathematical model, the problem on natural vibrations of a square plate with constant thickness and fixed ends is solved. The approximate solutions obtained are compared with experimental data.
