Electromagnetic linear suspension actuators: BYDRecent Research Landscape

Mechanical friction and vibration in high-speed transport cause significant energy loss and component wear. These innovations utilize active electromagnetic levitation and linear propulsion to eliminate physical contact and improve motion efficiency.

What technical problems is BYD addressing in Electromagnetic linear suspension actuators?

Uncontrolled vehicle chassis vibration

(51)evidences

Mechanical energy from road irregularities is transmitted directly to the vehicle body, compromising ride quality and stability. Mitigating this energy transfer improves passenger comfort and tire-to-road contact.

Excessive chassis vibration transmission

(44)evidences

Uncontrolled kinetic energy transfer from road irregularities to the vehicle body causes passenger discomfort and mechanical fatigue. Mitigating this transmission improves ride quality and structural longevity.

Uncontrolled chassis vibration

(36)evidences

Inadequate damping of kinetic energy from road irregularities leads to poor ride quality and loss of tire contact. Eliminating these oscillations improves vehicle stability and passenger comfort.

Insufficient suspension force density

(34)evidences

Limited thrust output relative to actuator size restricts the ability to counteract high-frequency road disturbances. Overcoming this bottleneck allows for more responsive active damping in heavy vehicle applications.
