The paper is devoted to the identification of parameters of a controlled piezoelectric damper model and experimental verification of the damper model. The device model was developed in the form of a rheological structure. For numerical studies, a mathematical model describing the phenomena occurring in the damper was developed. The paper presents the results of simulation and experimental studies of the properties of the controlled piezoelectric damper. The damping force is controlled by means of a controlled piezoelectric valve. This valve enables the control of the damper’s characteristics by changing the flow resistance between the chambers of the hydraulic damper.IDENTIFICATION OF A CONTROLLED PIEZOELECTRIC DAMPER MODEL PARAMETERS
In this paper, a mathematical model of a piezoelectric damper (PZD) is presented.
Moreover, identification of model parameters is described and compared with results of direct experiment.
Device model was developed as a rheological structure. Set of mathematical equations was used to describe the phenomena occurring in the PZD. Damping force realized in PZD is controlled by piezoelectric valve. This piezoelectric valve allows controlling the fluid flow between damper chambers. In that way control of dissipations characteristics of the piezoelectric damper is possible. In this paper are also presented results of numerical and experimental studies. (…)
