Machine foundations have to be designed as vibration resistant in order to ensure the continuous and safe operation of machines. Appropriate design measures securing operational stability under cyclic loading are therefore required. For this purpose, fatigue analysis has to be carried out accordingly.
Technical and economic factors necessitate in many cases the application of isolation measures. An ‘‘active isolation’’ prevents vibration effects induced by the machine to the surrounding structure, whereas a ‘‘passive isolation’’ minimizes disturbance effects induced by the machine to the surrounding structure. A sufficiently designed isolation can generally achieve active as well as passive isolation effects.
