Active control of vibration in small and medium amplitude range of elements in automotive systems

In this paper two different visco-elastic suspensions active system with pneumatic cylinder, and semi-active system with piezoceramics, are presented. The active suspension controls the vibration in medium-amplitude range and low frequency excitation. The semi-active suppression system controls the...

Description
Summary:In this paper two different visco-elastic suspensions active system with pneumatic cylinder, and semi-active system with piezoceramics, are presented. The active suspension controls the vibration in medium-amplitude range and low frequency excitation. The semi-active suppression system controls the vibration in the audio frequency range and small amplitudes. The main aim of proposed solutions is to decrease the amplitude of vibration in resonance of conventional, passive suspensions. Both systems are worked out, especially for the better protection of the human body against harmful sounds and vibrations.
