Hexagonal Linear Electromagnetic Actuator for Vehicular Suspension Systems

This paper is motivated by the growing interest in advanced vehicular suspension systems aimed at improving dynamic performance, control flexibility, and energy efficiency, key drivers in modern transportation electrification. In this context, it proposes a novel hexagonal linear electromagnetic actuator with permanent magnets, designed to deliver high force density while simplifying manufacturing. The methodology includes defining performance requirements for vehicular suspension applications, developing the electromagnetic design of the actuator, and validating it via finite element method simulations. A systematic approach is used to derive dynamic model parameters through numerical techniques. The performance of the actuator is assessed through simulations in active and semi-active suspension configurations. Results demonstrate that the proposed actuator provides high force density and effective dynamic response in a semi-active suspension system, indicating strong potential for application in next-generation automotive technologies.
