Research of Dynamics of Seat Air Suspension with Possibility of Vibration Energy Recuperation Under Action of Typical Harmonic Disturbances

This paper presents the results of the modeling of the new system of the seat suspension operation. The advantages of the proposed suspension system are potentially good vibration insulation characteristics and the possibility of vibration energy recuperation. The main feature of the proposed system is the application of additional air volumes and the air motor connected to the tachogenerator for the recuperation of vibration energy in electric energy. Harmonic kinematic disturbances (a sinusoidal signal with various frequencies and amplitudes) were used to research operation of the proposed seat suspension. The results show that this seat suspension can effectively operate in most considered conditions and have better vibration insulation characteristics than a standard seat suspension. Moreover, the inner processes of seat suspension were studied and the values of recuperated energy are presented. The values of transmissibility for various conditions are also presented.
