Embodiment

[0037] figure 1 It is a schematic diagram of the device structure for a maglev train model test of the present embodiment, referring to figure 1 , Permanent magnets are installed on both sides of the maglev train model, and the device includes: U-shaped track, two rollers and a base.

[0038] Two rotating induction motors (1# and 2#), two frequency converters (1# and 2#), speed encoders and digital display instruments are respectively installed on the base; two rollers (1# and 2#) The shaft center is perpendicular to the base, and is respectively connected with two rotating motors through rotating shafts. The two rotating motors turn in the opposite direction, and the working state of the rotating induction motor is controlled by the frequency converter to make it work in an electric state, which drives the drum to rotate, and produces relative motion with the permanent magnets on both sides of the car model to make the train model levitate.

[0039] The two frequency conver...

Abstract

The invention provides a magnetically levitated train model demonstrating and testing device. The magnetically levitated train model demonstrating and testing device comprises a U-shaped track, two rollers and a base; two rotary motors, two frequency converters, a speed coder and a display are respectively installed on the base; the axes of the two rollers are vertical to the base, and respectively connected with the two rotary motors through rotating shafts; the U-shaped track is fixed on the base; a displacement sensor and a three-dimensional force sensor are installed on the base between the U-shaped track; the two rollers are symmetrical by taking the U-shaped track as the centre; the upper and lower sides of the outside surfaces of the two rollers are each installed with an annular copper plate; each rotary motor is in circuit connection with a frequency converter, and then, connected to the speed coder and the display; and the displacement sensor and the three-dimensional force sensor are connected to the display through the circuit. The device can detect the three-dimensional force, the running speed and the suspension height of a magnetically levitated model directly and accurately; and thus, whether a magnetically levitated train model achieves the design standard or not can be judged.

Description

technical field [0001] The invention relates to the technical field of electric traction transmission, in particular to a device for demonstrating and testing a maglev train model. Background technique [0002] Maglev train is an emerging modern means of transportation. It not only has the advantages of low noise, strong climbing ability, safety and environmental protection, low maintenance cost and small radius curve passing ability, but also an electromagnetic levitation train without wheel-rail contact. Not limited by adhesion. The engineering demonstration of the maglev train needs to be demonstrated through the experimental model, and various working conditions in the experimental research and development stage also need to be verified and analyzed through the experimental model; the levitation height of the maglev train will change during operation, so in the test stage It is necessary to obtain various performance indicators of the motor under different levitation he...
