The predetermined value of the formula of half T of total engagement time that 340 employings of processor/memory cell are above-mentioned and looping mill rolling process to be simulated is determined T engagement time, and it equals the cycle of engaged section and the cycle that breaks away from section.The time T of each engagement and disengaging section is divided into a plurality of equal discrete times at interval then, and its each engagement and disengaging section have the cycle of calculating as mentioned above.For each time interval, adopt the formula of aforementioned calculation E (t) to calculate depth of engagement E by processor/memory cell 340.From each depth of engagement E of calculating, processor/memory cell 340 is determined corresponding sledge position.Processor/memory cell 340 also adopts the formula of above-mentioned calculating Ve and Ae to determine the initial tooth top speed and the initial tooth top acceleration of engaged section.It also adopts definite end of a period tooth top speed and the end of a period tooth top acceleration that breaks away from section of formula of aforementioned calculation Ve and Ae.It provides discrete time interval and corresponding sledge position to motor controller 300 then, and it is stored in information in the memory.

Reach its " 0 " afterwards at balladeur train 30, controller 300 makes servo linear motor 40 continue to drive balladeur train 30 towards first dull and stereotyped 100, make first and second dull and stereotyped 100 and 200 to mesh sample S, and further make second tooth 202 on second flat board 200 move to required depth of engagement E with respect to first tooth 102 on first flat board 100 _MGive in amplifier 360a, the 360b process in the generation appropriate driving signal, controller 300 is considered the position feedback information from linear encoder playback head 410, makes it to be compared with predetermined desired location by the physical location of the determined balladeur train 30 of the positional information that playback head 410 provides.Producing appropriate driving signal in the process of amplifier 360a, 360b, controller 300 is also considered the force information that is produced by force cell 84.

It is found that, when sample of web S not being provided between dull and stereotyped 100 and 200 and moving second flat board 200 when making that its tooth 202 is positioned to desired depth with respect to first tooth 102, the tolerance of sledge position need not force feedback information from force cell 84 just can be controlled to pact+/-10 microns.This is because second flat board 200 does not have power to be applied on first flat board 100 during engagement and disengaging section, even because second tooth 202 moves to required depth of engagement E with respect to first tooth 102 _M Second tooth 202 also never contacts first tooth 102.When Web materials sample S was provided, first and second teeth 102 and 202 produced a load during Web materials sample S engagement.This load should be by motor 40 counteractings to realize that sledge position is accurately controlled to less tolerance, for example about+/-10 microns to approximately+/-35 microns.Therefore, controller 300 increases offer the driving signal of amplifier 360a, 360b, so that the power that 40 pairs of balladeur trains of motor 30 are produced is substantially equal to the amount of the size of force cell 84 detected power.

Second flat board 200 with respect to first flat board 100 according to discrete time at interval and the rectilinear motion of the corresponding depth of engagement cause the operation simulation sample S that sample S is done to pass a pair of looping mill rolling roller R ₁And R ₂The time its operation that sample S has been done.The motion of the balladeur train 30 that controlled device 300 is controlled typically causes the outer top portion 202a of second tooth 202 to defer to the position to the time graph curve shown in Figure 14 A for example.Zero position 0 is the position when second tooth 202 on second flat board 200 just runs into a plane of determining between first and second teeth 102,202.

During the linearity range that advances, tooth top acceleration (corresponding to the balladeur train acceleration) is reduced to zero, makes tooth top speed be maintained at a constant value.When it when positive acceleration changes to negative acceleration, this section is used for cushioning any vibration of balladeur train 30.With the time set of this section is for example 2.0 milliseconds of predetermined values, and typically during all looping mill rolling process simulations, for the same time of this section employing.End of a period tooth top acceleration must equal zero, and end of a period tooth top speed must equal the to advance initial tooth top speed of changeover portion, referring to embodiment described below.

During the accelerating sections that advances, balladeur train 300 accelerates to the end of a period speed of the initial velocity of the linearity range that equals to advance from position 0 speed of beginning with fixed ratio.The balladeur train original position is determined by engineer/technical staff and is relevant with balladeur train " 0 ".Typically its equal or be approximately equal to balladeur train 30 can be away from the ultimate range of its " 0 " location.Among the described below embodiment, it is set at the 70mm place.The distance that the distance of this section equals former distance of positions balladeur train " 0 " deducts the distance (being 8.485 in an embodiment) that balladeur train 30 moves during advance linear and the changeover portion that advances.The time of this section does not pre-determine.The positive constant acceleration (that is tooth top acceleration) of the balladeur train 30 that will the quicken initial tooth top speed from 0 speed to the linearity range that equals to advance is determined in unit 340 in the preset distance of this section.

For breaking away from Duan Eryan, processor/memory cell 340 determines that by the above-mentioned formula that calculates T balladeur train 30 is in their maximum engagement degree of depth E with respect to first tooth 102 on first flat board 100 from second tooth 202 on its second flat board 200 at first _MThe position move to its " 0 " required time T.Thereafter, unit 340 determines that time T break away from divided by preset time gap periods (this cycle is determined as mentioned above) a plurality of discrete time interval of section.Unit 340 is determined then for the position of engagement in each discrete time interval or tooth top position E (equaling the sledge position apart from " 0 "), tooth top speed (it equals carriage speeds) and tooth top acceleration (it equals the balladeur train acceleration), referring to embodiment described below, wherein the total time T of this section equals 9.19 milliseconds.
