Hydraulic Regenerative Actuators

Abstract

In order to enhance the vehicle fuel economy, ride comfort and handling, this paper presents the planning, modeling, and performance study of a completely unique hydraulic pumping regenerative suspension supported an energy regeneration unit and a hydraulic actuator. It can harvest energy from suspension vibration and lessen damping oil temperature rising. additionally , variable damping force are often achieved by controlling the electrical load of the energy regeneration unit, and proper asymmetric ratio of compression/extension damping force needed by traditional vehicles are often obtained via the special layout of this suspension. It shows that an optimal regenerative power 33.4 W are often obtained from each regenerative suspension via the GA optimization. The physical based model and parameter study during this paper are often utilized in the regenerative suspension semi-active controller design and therefore the development of this novel hydraulic pumping regenerative suspension within the future.
