The solenoid type DC electromagnet set in the present invention inside can, can be one of direct current during calculating
Magnetic field approximation caused by magnet regards stationary magnetic field as, remembers that magnetic induction intensity caused by the axle of end is B, and another DC electromagnet produces
The relative stationary magnetic field of raw homopolarity, then regard one of them as iron conductor so long in approximate calculation, then meeting between two stream electromagnet
Magnetic repulsion is formed, is the repulsion F suffered by the conductor.For electromagnet is produced larger magnetic field under smaller current with formed compared with
Big magnetic repulsion, its iron core can use MnZn power ferrite PC44, and another electromagnet its effect is to form a homopolarity phase
To iron conductor, therefore its iron core can use in general ferrite, reduce cost, therefore be calculated as follows：

μ0；Space permeability, μ0=4 π × 107H/m, B:The magnetic induction intensity of electromagnet；
μr:The magnetic conductivity of iron core (temporarily taking MnZn power ferrite JP4), μr=2300 ± 25%；
A:The magnetic pole area of electromagnet, A=π r2；
n；The number of turn of electromagnet coil；1；The size of electromagnet coil current；
β1, β2：Helix tube electromagnet end center point and the angle at helix tube both ends；
Bs:The saturation induction density of iron core, Bs=510mT (25 DEG C)；
2) analysis, is calculated：
Deceleration panel 1：Width is generally 30-40cm, and diameter of tyres is generally 40-60cm, passes through deceleration in automobile
During panel 1, it, which is pushed when height is 3mm~15mm, can play the effect effectively slowed down.Automobile gross weight typically can be taken as 3-
5t, it is 3t temporarily to take automobile gravity, then each tire undertakes gravity G as the 1/4 of automobile gross weight.From equalising torque：Magnetic is denounceed
When the reducible half for taking gravity of power F, i.e. F=1/2G, can also meet condition because magnetic repulsion F is much smaller than automobile gravity, therefore calculate
Multiplied by with a reduction coefficient 1/2, then magnetic repulsion is F=1/4G.
Temporary power taking magnet coil number of turn n is 20, and coil current 1 is 30A, iron core magnetic permeability μrFor 2300, iron core (coil)
Radius r is 5cm, then nowAccording to formula B=445.88mT≤Bs, now FReprimand=1.243KN, it is known that
The magnetic repulsion is very big, illustrates that two pieces of electromagnet stress push one lag time of (＞ 15mm) needs completely.
When high speed car (takes vIt is high=80Km/b) when crossing deceleration strip, the time that single-wheel passes through isIt is less than
The time that two blocks of electromagnet can be pushed effectively, therefore electromagnet can not subdue when speed car moment passes through deceleration strip, so as to play
The effect slowed down to speed car.
When low-speed vehicle (takes vIt is low=1Km/h) when crossing deceleration strip, the time that single-wheel passes through isIt is now electric
Magnet automobile by when can subdue, then serving makes the purpose that passes through of slow moving vehicle smooth-going.
When between above two speed, the time required to can effectively being pushed with magnet by the time of deceleration strip according to it
Relation, can obtain different slowing effects, flexibility is very strong.
3) core dimensions, price, are calculated：
Iron core uses MnZn power ferrite PC44, is 0.5mm per circle coil radius, therefore desirable iron core is highly 3cm.I.e.
Physical dimension is:50mm × 50mm × 30mm, price 500 yuan/kg, density 4.8g/cm3。
It is 500mT to take B, and automobile total force is 4t, then repulsion caused by one side magnetByObtain A=12.56 × 10-3m2, a height of 3cm is taken, now, quality m=4.8 × 103×12.56×10-3×
0.03=1.81kg, price w=1.81 × 500=905 member.
