“…Furthermore, it is worth noting that the harvested voltage and power from a proposed car suspension system with the PZT stack cannot be compared with the other systems found in the literature. The harvested systems are different in the configuration (cantilever 10‐12 and stack 13‐16 ), location of the piezoelectric element in the suspension system (springs, 4‐6,16,17 shock absorbers, 12‐14 and wheels 7‐10 ), the suspension system model (quarter 5,7,10,12,16 or half‐car model 6,17 ), and the road input excitation (harmonic 5,6,13,16 or random 7,10,12,14,17 ).…”

“…Abdelkareem et al 3 reported that the harvested power from a medium‐size vehicle was around 350 W, while for the off‐road vehicle, the possible harvested power could reach over to 1 kW. In car suspension vibration, there are many ways of harvesting the vibration energy such as piezoelectric, 4‐18 electromagnetic, 19‐23 electrostatic transducers, 24 linear electromagnetic shock absorber, MR electromagnetic regenerative damper, hydraulic, rack‐pinion, ball‐screw, and cable/pullies 3,25‐29 . Piezoelectric transduction is one of the most used harvesters due to its simplicity, ability to operate in the wide frequency range, good electromechanical coupling effect, and providing the highest power density 30‐34 .…”

“…There are several locations of installing the piezoelectric material in the car suspension system. Piezoelectric patches could be implemented in the car suspension springs, and from the road irregularities, they will strain and then produce an electric charge across their terminals 4,15 . Namuduri et al 4 built a piezoelectric harvester that was attached to the vehicle spring assembly.…”

The main objective of this work is to build a mathematical model to evaluate the potential of harvesting power from the car suspension system. Quarter‐ and half‐car models with built‐in piezoelectric stack were modeled mathematically and simulated using MATLAB/Simulink. The piezoelectric stack was installed in series with the suspension spring to maintain the performance of the original car suspension system in ride quality and comfortability. The harvested voltage and power were tested with respect to time and frequency. From a half car model, the maximum generated voltage and power at the excitation frequency of 1.46 Hz were 33.56 V and 56.35 mW, respectively. By comparing a half‐car model with the quarter‐car model, the outcomes illustrated that the harvested voltage and power of the half‐car model were increased by 75.6% and 53.4%, respectively. Piezoelectric stack parameters (number of stack layers and area to thickness) and the car suspension parameters (sprung and unsprung stiffness, damping coefficients, and masses) were examined for half‐car model. Also, the influence of road amplitude unevenness was considered. The simulation results of the quarter‐car system were verified with the experimental test under harmonic excitation. The results exhibited good agreement with the simulation results at different excitation frequencies.

“…[1,2]. There are several mechanisms discussed in harvesting car's mechanical vibrations such as, attaching multiple piezoelectric harvesters [3][4][5][6][7][8][9][10][11][12][13][14], electromagnetic [15][16][17][18][19], electrostatic transducers [20], linear electromagnetic shock absorber, MR electromagnetic regenerative damper, hydraulic, rack-pinion, ball-screw, and cable/pullies [21][22][23][24][25][26]. However, Piezoelectric harvester is one of the most efficient and desirable transducer because of its simplicity, operate in the wide frequency range, excellent electromechanical coupling, and producing the highest power density [27][28][29][30].…”

A significant contribution of this paper is developing a half car model with a built-in piezoelectric stack to evaluate the potential of harvesting power from the car suspension system. The regenerative car suspension system is modelled mathematically using Laplace transformation and simulated using MATLAB/Simulink. Two piezoelectric stacks are installed in series with the front and rear suspension springs to maintain the performance of the original suspension system in ride quality and comfortability. Half car model is subjected under harmonic excitation with acceleration of 0.5 g and velocity of 9.17 rad/s. The harvested voltage and power are tested in both time, and frequency domain approaches. The influence of the different parameters of the piezoelectric stack (number of stack layers and area to thickness) and car suspension (sprung and unsprung stiffness and damping coefficients) are examined. Also, the effect of road amplitude unevenness is considered. The results illustrate that the maximum generated voltage and power at the excitation frequency of 1.46 Hz are 33.51 V and 56.25 mW, respectively.
