FxForce in the X direction is in newtons. m is2Is the mass of an iron ball with a diameter of 2mm, in kilograms. a isxAcceleration in the X direction is given in meters per second.
Fy＝m2×ay(2)
FyForce in the X direction is in newtons. m is2Is the mass of an iron ball with a diameter of 2mm, in kilograms. a isyAcceleration in the X direction is given in meters per second.

Sixthly, data correction:
6.1, correcting the initial speed of the motor,
in the actual motion state of the whole process, the motion formula is as follows
The actual formula is as follows:
the simplified formula:
in the case of known coincidence of reference lengths, i.e. S2＝S3T of simplified substitution equation (3) by parameter D4And (6) adjusting.

Thus S3＝S2Simultaneous (10) (12) (13) (14)
Can obtain the product
Is converted into
Because t is obtained3And t4In relation to each other, thus will t2As constants, the solution (16) yields:
due to time t1、t2、t3、t4Always positive, t "3＜0，t”3It is not true.
Therefore, it is not only easy to use
I.e. to obtain t2After the landing time, pass t3＝D×t4
To obtain
6.2 the arrangement interval formula of the permanent magnets is corrected,
cause calculation of Sx、SyAre all at t4The displacement in time is changed into acceleration movement, and the calculation formula in the unit time is
Then S can be obtainedWithin unit time after correction＝D2×SWithin a unit time
Then there are:
since the reference point S is knownCorrected x、SCorrected y. The planar track which is changed in the magnetic field environment and is expected to move in a variable speed mode can be obtained, the superposition of the planar arrangement projection area of the motion track and the permanent magnet is assumed to be adsorption, and the assumption is established when the adsorption condition is met. If the condition is not met, the process is carried out again by adjusting the spacingAnd (4) calculating in the previous step.
Seventhly, experimental demonstration:
the motion trajectory under the worst condition of the minimum magnetic force is calculated theoretically, so that the deviation exists from the actual calculation. Therefore, the actual arrangement needs to pass through a correction value C (defined as C being an actual track and a calculated model track in an actual motion state under the same model) under theoretical calculation. SAfter correctionThe values are in the X and Y directions, and the minimum value, namely twice S, is taken for ensuring the calculation reliabilityAfter correctionFor theoretical calculation of the arrangement distance G, the actual falling rate is 100% by using ten sets of experiments to release under the same conditions and different reference points and continuously adjusting the arrangement distance G of the permanent magnet.
