The Design of an Electromagnetic Linear Actuator for an Active Suspension 1999-01-0730

Through the support of the United States Tank and Automotive Command (TACOM), The University of Texas at Austin Center for Electromechanics (UT-CEM) has developed a prototype electromagnetic (EM) linear actuator suitable for vehicle active suspensions. The prototype actuator built was designed to be used in conjunction with a supplemental air spring. It is capable of producing 8,896 N (2,000 lb) of force with a 12.7 cm (5 in.) stroke and up to 1 m/s (40 in./s) velocity. The actuator was designed as a retrofit for military high mobility multi-wheeled vehicles (HMMWV). The design also focused on capability of being retrofit on a 18.1 kg (20-ton) metropolitan advanced technology transit bus (ATTB).
