Dynamics of two models (simplified and complex) of a small, typical vibrating table is considered in the paper. The table consists of vibrating plate and electrical vibrator, mounted in the central position of the plate, which excites the vibrations of the table. The coefficient of transversal stiffness of the spring has been determined on the basis of numerical simulation. The spring is an essential element of the system. The results of performed numerical simulations are presented in the graphical form.
