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.

Energy Harvesting Efficiency

Abstract With the recent energy crisis, the new energy harvesting technologies have become one of the hot spots in engineering academic research and industrial applications. By its wide range of application fields, vibration energy harvesting technologies have been gradually developed and utilized in which an efficient and stable harvester technology is one of the recent key problems. In order to improve energy harvesting efficiency and reduce energy loss caused by motor inertial commutation, many mechanical structures or hydraulic structures that convert reciprocating vibration energy into single direction rotation of motor are proposed. Although these methods can improve energy harvesting efficiency, they can have negative effects in some cases, especially in the case of vibration energy harvesting from human beings. This paper proposes a vibration harvesting mechanism with mechanical rectification filter function applied to backpack. The prototype model of the system was established in SolidWorks and imported into ADAMS. Thereafter, dynamic analyses of mechanical rectification filtering characteristics and meshing characteristics of one-way clutch were simulated in ADAMS. Based on ADAMS, parametric design analysis and its influence on the mechanical rectification characteristics were investigated. The simulation results were validated by bench test results. Simulation results is done by ADAMS and the results match well with bench test results.

Comprehensive Study

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.

Railway transportation has been increasingly significant for modern society in recent decades. To enable smart technology, such as health monitoring and electromagnetic braking for railway vehicles, a mechanical motion rectifier (MMR) based energy harvesting shock absorber (EHSA) has been proposed and proved to be capable of scavenging energy from the train suspension vibration. When installed on the train, MMR-EHSA works as a tunable damper in parallel with an inerter. This new suspension form brings great potential for further optimization of suspension dynamics but is rarely researched before. In this paper, the influence of the energy harvesting shock absorber (EHSA) on the railway vehicle dynamics performance is studied. A ten-degree of freedom vehicle model is established, with MMR shock absorber’s nonlinearity taken into account, with the purpose to analyze the influence of the EHSA on the ride comfort and wheel-rail vertical forces. Simulations are conducted by replacing the traditional shock absorber from train secondary suspension with the EHSA. Results show that EHSA could respectively harvest 180 W and 40 W average power at AAR 6th and 5th rail irregularity. In addition, compared with the traditional shock absorber, the MMR-EHSA can provide a higher ride comfort for passengers and slightly reduce the wheel-rail contact force.

Regenerative Shock Absorber

To reduce energy consumption or improve energy efficiency, the regenerative devices recently have drawn the public’s eyes. In this paper, a novel hydraulic energy-regenerative shock absorber (HERSA) is developed for vehicle suspension to regenerate the vibration energy which is dissipated by conventional viscous dampers into heat waste. At first, the schematic of HERSA is presented and a mathematic model is developed to describe the characteristic of HERSA. Then the parametric sensitivity analysis of the vibration energy is expounded, and the ranking of their influences is k1≫m2>m1>k2≈cs. Besides, a parametric study of HERSA is adopted to research the influences of the key parameters on the characteristic of HERSA. Moreover, an optimization of HERSA is carried out to regenerate more power as far as possible without devitalizing the damping characteristic. To make the optimization results more close to the actual condition, the displacement data of the shock absorber in the road test is selected as the excitation in the optimization. The results show that the RMS of regenerated energy is up to 107.94 W under the actual excitation. Moreover it indicates that the HERSA can improve its performance through the damping control.
