المستخلص: At present, with the progress of science technology materials appeared construction materials with high mechanical properties (high-strength, high-damping and light..etc) and a sophisticated vibration isolation systems. It is also accompanied by the development of methods of analysis and structural design and prosperity aware software and electronics all contributed significantly to the in-depth study of vibration buildings more comprehensive than its predecessors and at the same time meet the requirements for the design of civil - architecture. In case of machines founded on the floor there exist a dilemma of simultaneous solution of the active and passive vibration isolation problem. Complex approach to design of vibration isolation of machines should take into account transmission path of vibration in the building; from the source to vibration sensitive objects. Relationships between signals in the dynamic machines-building-precision machines" system can be determined based on the model built of rigid finite elements. Based on the equations of motion of the system its dynamic structure, subsystems transfer functions and cross-couplings between subsystems were determined. The influence of these couplings on transfer function which describes relationship between displacements of the precision machine and forces generated in the dynamic machine was examined.
