This research is a development of previous research entitled "Designing Regenerative Shock Absorber as a Vibration Energy Harvesting Tool on Vehicles" in the PUPT scheme funded by PNBP UNP 2017. In this study optimization of design oriented to energy generation was carried out while also paying attention to aspects driving comfort that might change due to the installation of a harvesting energy mechanism. One aspect of the change occurred in the type of magnet used, namely a ring type magnet with a type of neodymium material.From the test results obtained by changing the value of the efficiency of the shock absorber after the ERSA mechanism is installed by 2%, this condition also has an impact on the dissimilarity of the attenuation value obtained by 2% for the front-rear (left) and (right) wheels. In terms of generation voltage obtained the maximum generation voltage obtained is 25,600 mV. Based on the data obtained, it needs further development ERSA, especially in the aspect of the electromagnetic mechanism to optimize the generation of electrical energy.

Hydraulic electromagnetic energy-regenerative shock absorber is a new kind of shock absorbers, who can perform the function of a standard shock while acting as an additional source of power. One of the core components of this new shock absorber is the valve system. And its function is to rectify the direction of the oil flow. Then the oil can flow through the hydraulic motor from one port only no matter in expansion stroke or compression stroke. The research focused on the compactness, sensitivity and energy recovery rate of two different valve systems. And the results showed that the valve system composed of check valves better matched the hydraulic electromagnetic energy-regenerative shock absorber.

Energy-Harvesting Shock Absorber (EHSA), as a large-scale energy-harvesting mechanism for recovering suspension vibration energy, has been studied for years. A design of the regenerative shock absorber with Mechanical Motion Rectifier (MMR) has been proved to be more reliable and efficient. This paper reports a comprehensive study of the influence of MMR-based Energy-Harvesting Shock Absorber (MMR-EHSA) on vehicle dynamics performances. Models of MMR-EHSA and vehicle with MMR-EHSA with two degrees of freedom are created. Simulations are conducted on five typical vehicles, including passenger car, bus and three types of trucks. The ride characteristics of comfort, road handling and energy recovery are evaluated on these vehicles under various MMR rotational inertia and harvesting damping. The simulation results show that MMR-EHSA is able to improve both the ride comfort and road handling simultaneously under certain conditions over the traditional shock absorbers, which broadens our knowledge of MMR-EHSA’s applicable scenarios.

Hydraulic electromagnetic energy-regenerative shock absorber (HESA) is a new type of shock absorber which can regenerate a portion of energy dissipated as thermal energy in conventional shock absorber. This paper briefly describes HESAs working principle, uses AMESim, a hydraulic simulation software, to get damping characteristic of HESA as well as conventional passive shock absorber by doing some simulation tests, and contrasts the two consequents. Simulation results show that HESA has its unique damping characteristic, and its regenerative characteristic performs well.

Hydraulic-electromagnetic Energy-regenerative Shock Absorber (HESA) has been proposed recently, with the purpose of mitigating vibration in vehicle suspensions and recovering vibration energy traditionally dissipated by oil dampers simultaneously. The HESA is composed of hydraulic cylinder, check valves, accumulators, hydraulic motor, generator, pipelines and so on. The energy conversion from hydraulic energy to mechanical energy mainly depends on the hydraulic motor between two accumulators. Hence, the dimension match and parameter settings of hydraulic motor for the HESA are extremely important for efficiency of the whole system. This paper studies the methods and steps for dimension matching and parameter settings of the hydraulic motor in a case of a typical commercial vehicle. To evaluate suspension’s vibration characteristics, experiments on the target tour bus have been done. Simulations are conducted to investigate the effects of the hydraulic motor in different working conditions. The simulation results verify that the methods and steps adopted are accurate over a wide range of operating conditions and also show that appropriate matching and parameter settings of the hydraulic motor attached in the HESA can work with high efficiency and then effectively improving energy conversion efficiency for the whole system. Therefore, the theory of the matching progress can guide the future design of an HESA.

With the increasing development of railway transportation, the wheel-rail wearing problem is becoming more and more serious while the increasing of both the operating speed and loading weight of railway vehicles. Active radial bogie is one of the hotspots for research in the area of decreasing the wheel-rail wearing issues. Meanwhile, the energy dissipation problem has been restricting its development. This paper puts forward a novel energy-harvesting active radial bogie for rail vehicles. Making use of the hydraulic electromagnetic energy-regenerative shock absorber, the vertical vibration energy could be harvested while train is traveling. Detailed study and evaluation for this active radial bogie will be presented. The tests and simulation results prove the effectiveness of the proposed bogie mechanism and control.

Abstract This article intends a hybrid energy harvesting shock absorber design which comprehends energy harvesting of automobile suspension vibration dissipation. A mathematical model of the energy harvesting prototype is established, and simulation results show that the dissipation energy can be recovered by varying the feed module, thereby got the damping forces ratio at different compression and extension stroke. The energy conversion from hydraulic energy to mechanical energy mainly then mechanical energy converted into electrical energy furthermore we can rechange our battery from this recovered energy. The advanced mathematical model and prototype proposed maximum ride comfort meanwhile recovered the suspension energy and fuel saving. This article shows the simulation results verifying it with prototype test results. The damping force of expansion stroke is higher than the damping force of compression stroke. The damping characteristics curves and speed characteristics curves verify the validity by simulation and prototyping damper at different amplitudes of off-road vehicles. The Hydraulic Electromagnetic Regenerative Shock Absorber (HESA) prototype characteristic is tested in which 65 watts recovered energy at 1.67 Hz excitation frequency. So, 14.65% maximum energy recovery efficiency got at 20 mm rod diameter and 8 cc/rev motor displacement. The damping characteristics of the HESA prototype examined and it has ideal performance as the standard requirements of the National Standard QC/T 491–1999.
