“…As the movement in the vehicle suspensions is translational, the generation of a rotationally variable magnetic field requires a mechanism that converts translation into a rotation. These are well-known systems: rack-pinion [21][22][23], hydraulic [24][25][26][27][28][29], ball-screw [30][31][32][33], and some more exotic such as the "Linkage mechanism" [34], "Two-Leg motion" [35], or using flywheel drive [36]. All these systems have their own equivalent inertias, backlashes, and frictions affecting the dynamic behavior of the shock absorber and, therefore, the vehicle.…”

Numerous authors have studied Energy Harvesting Shock Absorbers (EHSA) over the last decade, proposing different designs with diverse geometries, parameters, and components. This article analyzes the energy recovery potential of two types of rotational EHSA, those that use ball-screw and those based on cable transmission. This paper presents the design, manufacturing and mathematical modeling of both options as well as the estimation of the potential power recovery with both technologies. Two types of vehicles are used as references, each one with the characteristic curves of their shock absorbers. Results are presented for different vehicle speeds and road types. Finally, some qualitative characteristics of both EHSAs are detailed to be taken into consideration for their possible use in vehicle suspension.

“…The semiactive suspension's recovery efficiency is as high as 77.72%, guaranteeing the damping effect. Besides, Xie et al [22] designed an energy regenerative shock absorber composed of multiple controlled generators, where each power generation mechanism consists of two rotating electric machines and a ball screw mechanism. The damping coefficient is changing by controlling the number of generators used and adjusting the external adjustable resistance.…”

The active suspensions have high energy consumption problems, while energy-regenerative suspensions have limited performance in improving vibration effects. In order to make up for the contradiction between the dynamic performance of the suspension and the energy consumption, this paper uses a linear motor with a bidirectional Buck-Boost circuit to design a multifunctional controller. On this basis, Energy-Consuming Active Control (ECAC) and Regenerative Semi-Active Control (RSAC) strategies are proposed. They make full use of the motor's characteristics in different working areas and improve the scope of application of the suspension. Besides, to ensure that the motor current can accurately track the target value, the inner loop controller uses fuzzy PID to achieve it, which improves the controller's adaptability and reduces the need for the mathematical model of the control object. The simulation results show that the proposed control circuit can achieve the required control effect. Under the active control strategy, the ride comfort of the vehicle is improved by about 27%, and other performances are also controlled within an appropriate range. In the energy-regenerative mode, not only is the energy recovered, but the vehicle ride comfort is also improved by about 10%. Compared with the traditional single-performance suspension, the proposed suspension system improves the suspension's overall performance and satisfies different driving conditions and driver needs.

“…Demetgul and Guney presented a hybrid EHRSA, wherein energy harvesting was possible through both hydraulic as well as electromagnetic mechanisms. Xie et al came out with a somewhat different model of hydraulic EHRSA with multiple generators individually controlled by switches. The main feature of this model was real‐time tuning of damping coefficient according to the road conditions, while offering higher energy harvesting efficiency as well.…”
