Abstract
The performance of a passive-levitation vehicle is improved for moving over a path. The vehicle has a levitation skid slidable on the path and capable of developing a levitation force to support a compartment at a certain distance from the path. A suspension between the compartment and the skid, comprises a kinematic structure to confer degrees of freedom and relative constraints between the skid and compartment; a passive elastic element connected between the skid and the compartment; and a controlled-dynamic element able to exert a force having controlled dynamics between the skid and compartment; the passive elastic element and controlled-dynamic element mounted in parallel to each other and connected to the skid and compartment. sensor detects the distance between the skid and the path. An electronic circuit, connected to the sensor and to the controlled-dynamics element, carries out a feedback control to adjust this distance.
