Parameter design for a vibration absorber with time ...

Jan 18, 2019 · Abstract. Traditional passive vibration absorbers are effective only when their natural frequencies are close to those of the excitations. To solve this problem, a vibration absorber with time-delayed feedback control is proposed to suppress vibration of the primary system under excitation with changing frequency.

Vibration Isolation Theory of Foundations - Fabreeka

hammers, centrifugal pumps and compressors are the most predominate sources of vibration and shock. If the equipment requiring isolation is the source of unwanted vibration (Figure 1), then the purpose of isolation is to reduce the vibration transmitted from the source to its support structure. This vibration
