“…The degrees of freedom include the vertical movement of the sprung and unsprung mass . The road disturbance is typically modeled as a white noise disturbance with a first-order filter [13], i.e., (8) Together with a gain for the white noise , which is fitted on a sample time of 1 ms, various road types can be described, depending on the forward velocity and the shaping parameter . The power spectral density (PSD) of the measured road profile as a function of the spatial frequency is calculated through the method described by Welch [14].…”

“…In addition, the ability of regeneration, although limited [7], makes these systems more suitable due to the importance of reduced CO emissions. Due to the development toward HEVs, electromagnetic suspension systems are easier to implement, because HEVs have their own energy storage system, which controls the peak power demand and regenerative power of the active suspension system [8]. Finally, these systems offer an increased bandwidth of about a factor 10, relative to hydraulics and pneumatics, which drastically improves the performance with regard to the comfort, stability, and flexibility of full vehicle control.…”

Abstract-The efficiency and power consumption of a direct-drive electromagnetic active suspension system for automotive applications are investigated. A McPherson suspension system is considered, where the strut consists of a direct-drive brushless tubular permanent-magnet actuator in parallel with a passive spring and damper. This suspension system can both deliver active forces and regenerate power due to imposed movements. A linear quadratic regulator controller is developed for the improvement of comfort and handling (dynamic tire load). The power consumption is simulated as a function of the passive damping in the active suspension system. Finally, measurements are performed on a quarter-car test setup to validate the analysis and simulations.Index Terms-Active suspension, permanent magnet actuator, quarter car .

“…The results also indicated that the harvesting power from vehicle suspension was proportional to tire stiffness and road vertical excitation spectrum. Montazeri-Gh and Soleymani [10] researched an energy storage system (ESS) in hybrid electric vehicles, and the simulation results revealed that the use of hybrid ESS could improve the efficiency of the batteries, and it could increase their working life as the active suspension (AS) load fluctuations were transferred from the batteries to the capacitors. Xie and Wang [11] proposed a dualmass piezoelectric bar harvester which composed of a springmass system connected by a piezoelectric bar transducer which is equivalent to a spring and a damper in a mathematics model.…”

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 1 ≫ 2 > 1 > 2 ≈ . 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.

“…Both of these types include mechanical structures, which are driven by hydraulics. With the rising concern in global scale environmental issues, energy saving in vehicles and mobile machines is an important subject and reduction of fuel consumption is strongly required (Petrone, 2010 ;Saber, 2010 ;Bhattacharya, 2009 ;Montazeri-Gh, 2010 ;Mapelli, 2010, Liu, 2010. Hybrid propulsion concepts in working machines are emerging to improve their fuel economy and reduce CO 2 emissions (Fakham, 2011;Hui, 2010, Paulides, 2008.…”
