Automatically the cloth tube module is realized automatic stringing, order and the shortest scheme of axial overall length that the steel tube bundle is increased progressively by sequence number under the prerequisite that guarantees the adjacent tubes machining gap are in line from right to left, it is the circumference rotation of axle that being about to wait arrange pipe intersection constantly carries out with the center line, up to one-period 2 π, find it to adjust angle, this rotation search procedure for the treatment of stringing is called exploratory process to arrange axially movable ultimate range of pipe and corresponding circumference rotation.Whether mild and user's according to steel-tube intersection-line curvature actual requirement, this automatic cloth tube module provides two cover prioritization schemes to select (user can select and the replacing scheme by parameter setting module) for users.First kind is " precision is preferential ", promptly adopt exhaustive trial method, the exploratory process of the pipe of waiting to arrange is finished (for circumference cycles 2 π=360 ° with 1 ° of step-length, need to sound out 360 times), this method can guarantee error≤1 that the anglec of rotation in the optimal result adjusts °, thereby make no matter what kind of shape steel-tube intersection-line is, whether smooth, whether curvature is mild, the optimization of profile result is always optimum solution, but because the exploration number of times is too many, makes optimal speed relatively slow, especially work as steel pipe quantity more for a long time, inefficient drawback of its time is just more obvious.Second kind of scheme overcome the low drawback of time efficiency in first kind of scheme, adopts block research algorithm thought, is about to exploratory process respectively with step-length α, β ... γ, 1 ° finish (α＞β＞...＞γ＞1 °).Slightly find out earlier big step-length (α, β ... the exploratory anglec of rotation of optimum solution correspondence γ), be the center with this angle again, angle step that this exploratory process is got (α, β ... among the γ certain) for radius take out an interval as between new exploratory process optimum anglec of rotation seek area (for can get between complete section, before the big step-length of two-wheeled sound out search between the seek area two-end-point do not include computer capacity in, promptly take away the interval).At last with small step long 1 ° be to search (end points calculates, and promptly gets the closed interval) with the method for exhaustion between the final lock room of γ at radius.In this software module, take into account precision and time efficiency, the step-length of exploratory process is taken as 15 °, 5 ° and 1 °, make this process only need
Inferior finishing reduced 89.17% operation time, and manages under the milder situation of intersection curved transition at each, and the gained stringing result and the method for exhaustion are about the same.But this scheme gained optimization solution can not always guarantee to be optimum solution, especially when a pipe intersection curvature mild (for example at very little angular range inner curve waveform relief intensity big even cusp arranged) was arranged in adjacent two pipes, this was separated and can't guarantee to be optimum solution.Therefore, " precision is preferential " and " speed is preferential " two sets of plan has complementary functions, but since separately the characteristics of algorithm can't learn from other's strong points to offset one's weaknesses integratedly, the user can only get one (selecting by parameter setting module) according to actual needs.
