Computational and Theoretical Justification of Foundation Design Solutions for Equipment Subject to Dynamic Loads

The solution to the problem of foundation vibration jointly with the subgrade soil caused by dynamic loads generated by equipment is considered. Soil and foundation behavior, which has anti-vibration pads, can be described by the Voigt model of viscoelasticity. The explicit scheme was used in the algorithm of numerical calculation in time domain. Spatial discretization is carried out by finite element method. The analysis of the solution was conducted in order to compare this method with known analytical methods of foundation designing.
