1. An equipment for simulating high-speed magnetic levitation (maglev) operation, comprising:
a wheel;
a driving mechanism;
a first test guideway;
a second test guideway;
a first test object;
a second test object;
a first position control device; and
a second position control device;
wherein the wheel comprises a rim and a hub; the hub is arranged at a middle of the rim;
the driving mechanism is configured to drive the wheel to rotate;
the first test guideway and the second test guideway are arranged on an inner wall of the rim; the first test guideway is arranged on one side of the hub, and the second test guideway is arranged on the other side of the hub;
the first test object is arranged in the first test guideway;
the second test object is arranged in the second test guideway;
the first position control device is configured to control a reciprocating movement of the first test object along a radial direction of the first test guideway; and the second position control device is configured to control a reciprocating movement of the second test object along a radial direction of the second test guideway;
a vibration exciter is arranged above the first test object; a first six-axis force sensor is arranged between the vibration exciter and the first test object; the second test object is fixedly arranged on a first clamping arm; and a second six-axis force sensor is arranged between the second test object and the first clamping arm; and
the first test guideway is a circular Halbach permanent magnet guideway; the second test guideway is a circular metal guideway; the first test object is a high-temperature superconducting magnetic levitation test object; and the second test object is an electrodynamic levitation permanent magnet test object.
