It answers, and meets the relationship of Tn=K*Fn, K is coefficient.Specifically:
Expect layer tension: F1, F2, F3 ... ... Fn；
Corresponding output torque: T1, T2, T3 ... ... Tn.
The means of experiment this relationship it is more accurate change, firstly, in physics torque and power formula: M=L*F, this
In M torque be a vector, L is the arm of force, and F is that power is also a vector, the relationship of the torque T n in application scheme and tension Fn
It is being simplified by above-mentioned formula, foundation is: the first, tension, torque in mechanism are a fixed-direction, so only needing
Consider size relation；The second, the reduction ratio in the mechanism is a constant, can regard the L in above formula as, so obtain one
A Tn direct ratio and Fn(act on power on a guide, that is, the tension of material film) linear relationship；Specific derivation process is: this
In with COEFFICIENT K come instead of i.e. Tn=K*Fn, because the output torque characteristic of pneumatic clutch can be from the technology hand of product
It is obtained on volume, so Tn range is it is known that the transmission ratio of motor to the guide roller of mechanism is also known, so tension Fn and torque
Relationship K between Tn is easy for deciding, but above-mentioned relationship is ideally meeting in actual moving process
It is influenced by transmission mechanism frictional force, mechanical structure inertia, so needing further to refine K by experiment, the side of experiment
Method step is already described in the text, exactly measures several points by the method being segmented, then linearizes again again, that is, Tn=Kn*
Fn, Kn here are segmentations, and the more segmentation the more accurate, confirm COEFFICIENT K n by dividing ten sections in application scheme, can
Meet system control to require.
In the present embodiment, it is arranged before storage rack movement according to current system using the relationship of tension and output torque

Expect that frame runs the impact to system tension；The stability of tension depends on the relationship quantity of sampling quantity of measurement tension and output torque,
Analysis degree is higher, and its actual tension force stability is higher.
By using above technical scheme, the critical state of storage rack is judged using trend-monitoring mode, so that storage rack
Material film retractable process it is more stable；Using the relationship of tension and output torque, before storage rack movement, according to current system
The Tensity size of setting determines the value of storage rack ideal output torque, then by judging operation of the storage rack under passive state
Trend determines the ideal output torque of storage rack operation and the time point of transmission motor intervention, to reduce storage rack operation pair
The impact of system tension；By judging operation trend of the storage rack under passive state, to determine the desired electrical of storage rack operation
