Electromechanical Actuators for Active Suspension Systems.
Abstract
Electromechanical suspension actuators are devices intended to provide the force input called for by motor vehicle active suspension systems. Experimental active suspensions have been devised, in which hydraulic actuators provide the force input. Such systems leave much to be desired regarding safety to equipment and personnel. In addition, hydraulic actuators require an electromechanical valve to interface the electrical and hydraulic aspects of the overall system. Accordingly, electromechanical actuators are being studied as an alternative approach to active suspension design. Such actuators would provide a direct interface between electrical/electronic controls and the suspension dynamics, eliminating the need for hydraulic systems and their attendant problems of leakage and vulnerability to battle damage. The report that follows, describes the reason for studying electromechanical actuators, requirements such devices must meet, and various development programs. In addition, this report also describes various electric motor and actuator concepts that could serve as a point of departure for future electromechanical actuator development.
