Modelling and identification of hysteresis of Vacuum Packed Particles Torsional Damper

Year: 2025

Type: article

Abstract: This paper presents the modelling and identification of hysteretic behaviour in a Vacuum Packed Particles Torsional Damper (VPPTD) filled with ABS (Acrylonitrile Butadiene Styrene) polymer granulate. The presented device is an innovative member of the semi-active damper family, featuring real-time controllable damping characteristics. A series of experiments were conducted to observe the response of the damper under various loading conditions. The Modified Bouc–Wen model (MB-W) was employed to capture the non-linear hysteretic characteristics exhibited by the damper. Using an evolutionary algorithm, the parameters of the model were identified on the basis of experimental data. The identified parameters of the Modified Bouc–Wen model are described by underpressure functions. The proposed model was validated, demonstrating its efficacy in predicting the damper’s hysteretic behaviour under various operating conditions. This study contributes to the understanding and prediction of complex non-linearities in VPPs.
