Such as Fig. 3, it is long 700mm that section, which is the sectional dimension of rectangular suspension rail, wide 25mm, and suspension rail length is
2500mm.The sectional dimension of U-typed levitating electromagnet is long 700mm, wide 125mm, wide 25 mm of magnetic pole, single levitating electromagnet
Length is 1000mm, and the material of suspension rail and levitating electromagnet magnetic pole is Q235, and electromagnetism iron wire packet fills the section ruler of copper wire
Very little is 100mm*150mm, and the filling rate of copper wire selects 60% in electromagnet, and every square millimeter of maximum is selected to pass through the side of 1.6A electric current
Formula, the distance that selects to suspend is 8mm.
Show that two electromagnetism resultant forces between levitating electromagnet and suspension rail are 36562N by Finite Element Simulation Analysis,
It can convert as 3656Kg.The weight of floating unit and car body is undertaken by the electromagnetic force that levitating electromagnet provides, wherein suspension rack
Gross weight is 1700Kg or so, and car body gross weight is 1100Kg or so, and car body design has the space of a driver and four passengers, is carried
It resets and is set to 600Kg, in this way, the weight of integrated suspension adds up to 2900Kg, be less than 3656Kg.Realize driving function trolley by
In not suspending, so not considering trolley weight in the calculating that suspends.
Fig. 4 is the construction dimensional drawing of guiding electromagnet component, by taking right guided way 212 and levitating electromagnet 107 as an example.It leads
It is long 150mm to rail sectional dimension, wide 10mm, guided way length is 2500mm.The sectional dimension of U-typed guiding electromagnet is length
100mm, wide 45mm, the wide 10mm of magnetic pole, single guiding electromagnet length are 500mm, the material of guided way and guiding electromagnet magnetic pole
Material is Q235, and the sectional dimension that electromagnetism iron wire packet fills copper wire is 80mm*35mm, the filling rate choosing of copper wire in electromagnet
60%, select every square millimeter of maximum by way of 1.6A electric current, selective guide distance is 10mm.
Show that two electromagnetism resultant forces between guiding electromagnet and guided way are 422N, can be rolled over by Finite Element Simulation Analysis
Calculating is 42Kg.When floating unit is in center position in suspension box beam, the obstructed electric current of two guiding electromagnets is not necessarily at this time
Guiding force, when floating unit run-off the straight, guiding electromagnet is powered according to the inclined degree that orientation sensor reflects, and guarantees
Floating unit is restored to center position.
As seen from the above analysis, levitating electromagnet is capable of providing the suspending power met the requirements.When suspension controller provides properly
The electric current of size, so that the suspension suction that electromagnet generates is equal to the self weight of floating unit and car body, so that it may realize suspension function
Can, suspension controller controls the basis source of size of current in the measured value of suspended sensor.Guiding electromagnet energy is utilized simultaneously
The case where enough preventing floating unit from turning on one's side.
Compared to traditional suspension train system, the rubber tire burden under the structure is small, is conducive to increase service life, drop
Low-maintenance cost.
In conclusion a kind of three rail of separate type for suspension type magnetic-levitation train of the present invention suspends and drive system, entirely
System has structure simple, the feature of small size, low cost.The low speed such as traffic operation feelings between sight spot sightseeing, building can be served
Suspension type magnetic floating traffic tool under condition.
