Dynamic Analysis of the Turbine Unit Foundation in its Interaction with the Existing Foundation

The article is devoted to the issue of determining the parameters of the stress-strain state of the foundation of the turbine unit PR-30/35-90/10/1.2, installed in the building of the reconstructed Power Plant. The main difficulty in arranging a new foundation on the existing one is the issue of ensuring the joint operation of the two foundations, as well as reducing the amplitudes of dynamic oscillations of the foundation of the new turbine unit. To solve the problem, a three-dimensional idealized model of the foundation of a new turbine unit was developed, as well as a model of the existing foundation. The problem was solved in a contact formulation in order to be able to model the detachment of a new foundation from the existing one. The parameters of the SSS of the foundation of a new turbine unit are determined and recommendations are given to ensure their joint operation. Recommendations for the construction of mathematical models of the turbine unit - foundation system are formulated.
