A matrix dynamic equation of motion of a steel frame foundation for rotary machines, equipped with passive dynamic absorbers, is formulated. Transoms and columns of the foundation are made as thin walled bars of an open contour. The machines are treated as vibroisolated rigid bodies. The spatial thin walled frame is discretised with FEM. The system satisfies some orthogonality conditions, used in...
