The active suspension has undoubtedly improved the performance of the vehicle, however, the trend of "lowcarbonization, intelligence, and informationization" in the automotive industry has put forward higher and more urgent requirements for the suspension system. The automotive industry and researchers favor active energy regeneration suspension technology with safety, comfort, and high energy regenerative efficiency. In this paper, we review the research progress of the structure form, optimization method, and control strategy of electromagnetic energy regenerative suspension. Specifically, comparing the pros and cons of the existing technology in solving the contradiction between dynamic performance and energy regeneration. In addition, the development trend of electromagnetic energy regenerative suspension in the field of structure form, optimization method, and control technology prospects.

This article proposes a hybrid system for increasing the electric vehicles’ (EVs) driving range considering regenerative shock absorbers. The proposed hybrid approach is a combination of atomic orbital search (AOS) and wild horse optimizer (WHO); later, it was called AOSWHO method. The major objectives of the proposed work are to extend vehicle range, reduce the charging time of the vehicle, reduce the battery size, and increase the efficiency of vehicle. In this proposed work, linear Permanent magnet (PM) generators are used as the sole instrument and on-board source is utilized to absorb vibration energy of the moving vehicle. Here, the proposed method has four key modules: (a) suspension vibration input, (b) transmission mechanism, (c) generator module, and (d) power storage. A suspension vibration is mostly pretentious by road roughness and speed vibration, which is optimally handled by the proposed hybrid technique. The conversion of the alternating linear vibration into unidirectional rotation of generator shaft is processed by proposed hybrid technique. Based on the volume and efficiency of the dampers, a small volume, brushless DC motor with low rotor inertia is selected to produce electricity. By then, the proposed AOSWHO run on MATLAB site and its performance is related to several existing systems. From the simulation result, it is concluded that proposed system delivers an State of Charge (SOC) of 40.33, which is high compared to existing approaches.

“…Durante los últimos años, las investigaciones en este sentido se han orientado en el mejoramiento del mecanismo de conversión de movimiento, utilizando diferentes tipos de transmisiones mecánicas para aumentar la eficiencia de conversión de energía. Li et al [73] propusieron un novedoso mecanismo de conversión de movimiento vertical bidireccional usando dos cremalleras de roscas helicoidales opuestas, dos engranes helicoidales de diámetros diferentes y embragues unidireccionales (overrunning clutch) (Figura 13). Los resultados experimentales demostraron que la eficiencia máxima de conversión de energía mecánica del dispositivo fue de 65.02 %, considerando excitación de tipo armónica.…”

En este trabajo se presenta una revisión exhaustiva de los diferentes tipos de amortiguadores regenerativos utilizados para mejorar la reducción del consumo de combustible y de las emisiones contaminantes (principalmente el CO2) en vehículos comerciales. En primera instancia, se describe la interacción entre el tren motriz y el sistema de suspensión automotriz, incluyendo los ciclos de velocidad de conducción como el enlace principal. Posteriormente, se presenta un esquema gráfico del proceso de regeneración de energía vibratoria mediante amortiguadores regenerativos, considerando el sistema de almacenamiento de energía. Además, se discuten los avances tecnológicos recientes de los diferentes tipos de amortiguadores regenerativos, sopesando principalmente la filosofía de diseño del mecanismo de rectificación de energía vibratoria. Finalmente, se presentan las conclusiones y tendencias futuras sobre las aplicaciones de estos dispositivos en diferentes disciplinas de la ingeniería.
