Abstract
A vibration isolation scheme includes an interior sled mounted to a vehicle body by one or more sled isolators having damping properties. The sled floats with respect to the vehicle body to isolate vehicle occupants from vibrations otherwise transmitted from the vehicle body. The sled isolators can be located at specific vibrational nodes to target a particular frequency or a range of frequencies. The damping properties of the sled isolators can attenuate vibrations in ranges outside the target frequencies.
Claims20
A vehicle comprising:
- a vehicle body defining an interior for retaining vehicle occupants, the vehicle body arranged to receive vibrations transmitted throughout the vehicle;
- a plurality of seats for supporting vehicle occupants;
- a sled structure located within the body interior and including a floor portion to which the seats are mounted;
- and
- at least one sled isolator connected to the sled structure and to the body, the sled isolator having a damping property such that the sled structure and seats are isolated from the body vibrations.
2 more elements
A vibration-isolation system for a vehicle comprising:
- an interior sled having a floor portion defining a seat-mounting area adapted to support a plurality of seats, the interior sled located within an interior defined by a vehicle body;
- and
- at least one sled isolator connected to the interior sled and to the vehicle body, the sled isolator having a damping property for isolating the interior sled from vibrations of the vehicle body.
A method of constructing a vibration-isolated vehicle comprising:
- analyzing a vehicle body design to locate nodes of vibration;
- connecting at least one isolator component to the vehicle body at a location corresponding to at least one of the nodes of vibration;
- connecting an interior sled adapted to support passenger seats to the at least one isolator component so as to isolate the interior sled and passenger seats supported on the sled from vibrations of the vehicle body.
