Abstract
A vehicle testing system includes a wheel plate constructed and arranged to support a vehicle wheel. A linear electromagnetic actuator has a moving magnet mechanically coupled to the wheel plate constructed and arranged to impart a controlled substantially vertical force to the wheel plate. A spring may be mechanically coupled to the wheel plate to support at least a portion of a static mass of the vehicle.
Claims4
A system for testing a vehicle comprising:
- a plurality of apparatus, each of the plurality of apparatus comprising:
- a frame separate from the vehicle and configured to support at least a portion of a wheel of the vehicle;
- and
- a linear electromagnetic actuator at least partially contained within the frame, the linear electromagnetic actuator comprising a movable magnet and being constructed and arranged to impart a controlled substantially vertical force to a vehicle wheel;
- wherein each of the plurality of apparatus is arranged to independently impart controlled substantially vertical force on a corresponding one of a plurality of supported vehicle wheels;
- and
- a plurality of air springs constructed and arranged to provide leveling of a supported vehicle.
