“…The presented solution was introduced in order to decrease the demand for energy necessary to quickly refocus the PZ valve, which was obtained from the electric installation of a vehicle. In order to power a single PZ damper, it was necessary to supply power of 17 W. The change of voltage in the range 0-150 V enables lengthening the piezoelectric stack to the value of 85 μm when using PPA-80L actuator [34]. Results of experimental studies of the PZ damper are shown in Figure 4.…”

In this work an original construction of a vibration damper controlled by means of a valve with a short time of operation lag is presented. The valve-controlling properties of the damper regulates the flow of fluid between the chambers of the damper and was constructed using piezoelectric actuators, whose characteristic feature is the possibility to change dimensions, e.g., length, under the influence of voltage. As a result, by changing voltage it is possible to control the throttle of the flow by changing the width of a gap, which influences a change of damping forces. Such a solution enables a quicker change of damping forces than in other kinds of controlled damper. Due to the obtained properties, the damper may be applied to reduce the vibrations of vehicles and machines that undergo quick-change loads. In the article, the results of experimental studies of the aforementioned damper are presented. Based on the results, dissipative characteristics were determined. Also, results of numerical studies comprising the development of a numerical model of a controlled piezoelectric damper are shown. Results of numerical studies, as well as experimental studies, are presented in the form of dissipative characteristics. Comparison of results of numerical and experimental studies confirms the possibility to apply this kind of construction in semi-active systems of vibration reduction of vehicles and machines.

“…In order to model controlled dampers, the mathematical models most often used are the Gamota–Filisko and Bouc–Wen [ 18 , 34 , 35 ] models. In the case of the Gamota–Filisko model, rheological structure is shown using five parameters, and in case of Bouc-Wen using seven parameters.…”

“…With the initial parameters simulated at current input of 1A and low piston velocity ( Vp = 0.08 m/s), the values of damping force by MR effect is 2635.38 N and the dimensionless dynamic range, which is the ratio of total damping force to the viscous damping force, is 16.08. The optimized parameters are obtained through analysis of variance (ANOVA), the response surface method (RSM) help us to obtain the second order polynomial equation to illustrate the relationship between damping force by MR effect ( MR F ) and design variables is given below [9]. The initial and optimum solutions for design parameters of the hybrid type MR damper are shown in Table 1.…”

“…To achieve improved damping force, a novel hybrid type MR damper is designed where a permanent magnet is added to enhance the damping force and resolve the fail-safe issue. Olivier and Sohn proposed a hybrid type MR damper which consist of two permanent magnets apart from electromagnetic coil [9]. The simulated results proved that this type of damper can generate higher damping force than the normal type with an added advantage of fail-safe behavior.…”

This work presents the design optimization and numerical investigation results to evaluate the vibration control performance of a novel hybrid type magnetorheological (MR) damper. Since the proposed hybrid type MR damper has both an electromagnet and permanent magnets, it is possible to design a compact-sized damper with an improved damping force. After designing and characteristics analysis of the proposed hybrid type MR damper, optimization of design parameters is carried out to achieve enhanced damping force. The designed hybrid type MR damper is applied on both quarter and full vehicle models to evaluate its performance on suppressing the unwanted sprung mass motions such as heave and pitch motion. Skyhook and linear quadratic regulator (LQR) controllers are designed and incorporated to the vehicle system models to control the current input to the proposed hybrid type MR damper. The input current to this hybrid type damper is reduced while the damping force is enhanced compared with the conventional MR damper. All the numerically simulated results showed that the proposed hybrid type MR damper can improve the ride comfort and road holding capability on bump and random road conditions. Recently, a lot of works concerning semi-active suspension system featuring MR fluid

“…However, this model is complex, requires a larger volume, and exhibits a high friction force, which can decay its damping force. By contrast, hybrid models generate a high damping force and address the problem of failure safety for field-off [ 11 , 12 , 13 ]. To achieve model simplicity and compactness while improving its damping characteristics, Bai et al [ 14 ] proposed an annular-radial-duct MR damper to improve the efficiency of the MR damper.…”

In this study, a novel hybrid annular radial magnetorheological damper (HARMRD) is proposed to improve the ride comfort of an electric vehicle (EV) powered by an in-wheel motor (IWM). The model primarily comprises annular-radial ducts in series with permanent magnets. Mathematical models representing the governing motions are formulated, followed by finite element analysis of the HARMRD to investigate the distribution of the magnetic field density and intensity of the magnetorheological (MR) fluid in both the annular and radial ducts. The optimized model generates a damping force of 87.3–445.7 N at the off-state (zero input current) with the excitation velocity ranging between 0 and 0.25 m/s. By contrast, the generated damping force varies from 3386.4 N to 3753.9 N at an input current of 1.5 A with the same velocity range as the off state. The damping forces obtained using the proposed model are 31.4% and 19.2% higher for the off-field and on-field states, respectively, compared with those of the conventional annular radial MR damper. The efficiency of the proposed model is evaluated by adopting two different vehicles: a conventional vehicle powered by an engine and an EV powered by an IWM. The simulation results demonstrate that the proposed HARMRD along with the skyhook controller significantly improves both the ride comfort and road-holding capability for both types of vehicles.
