The vibration phenomena of edge mill was eliminated by decreasing rolling speed and controlling the speed difference with front mills within ±0.1m/s,optimizing small tension control program and rearranging draught schedule.
So it takes the minimum driving power of double transporting belt conveyer drawing electrical machine as the goal function, with the operating speed of conveying belt, its width, its minimum tension, interval of roller as variables of designing, considers the fuzziness of influencing restraining border and intensity of conveying belt, and the randomness of the gauge stress of conveying belt, sets up mathematical models of the fuzzy reliability optimal design on the main parameter of conveyer, uses the Hopfield neural network algorithm to ask solving to the model.
The manual design of overhead conveyers is replaced by computer aided design (CAD). The main problems such as date input or output and positioning the node with minimum tension is concretely described.
Test of mechanical tension and stimulations with electricity and carbachol were performed on the excitability and contractility of the detrusor strips from 8 patients selected from each of the groups in vitro . Results The minimum tension of the detrusor strips when contraction occurred in DI and DS was (0 324±0 132)g and (0 822±0 216)g, respectively.
This paper introduces the physical and chemical properties of nano-ceramirs powder, advanced the related sizing prescription bases on the property of nano viscose fabric and suggested a sizing process route of "slow speed,less tension,low drying and limited elongation".
Design mind of producing cotton bamboo blending elastic jean is introduced. Process demand and key technology of winding, warping, sizing & dyeing and weaving process is also introduced. Low tension, extent retention, low viscosity is adopted in sizing and dyeing process.
The tension that induced isolated detrusor contraction by mechanical pulling in DH and DI groups was lower than the control group,and the contraction frequence at the same tension was higher than the control group(P<0.05).
On the basis of the drive control characteristic of a multiroll extra light-gauge strip mill, the selection of the main driving motor and coiling motor of the domestically-made 30 high rolling mill is discussed to improve the control accuracy and stability of small tension when rolling 0.001～0.003 mm thick strips. Through the comparative test of two types of DC motors, the problems, such as the speed adjusting range, pulsed torgue and matching of armature voltage, are further analyzed.
The physicomechanical properties(KES-FB data)of fabrics after open blowing and decating finishings, and the dimensional stability of the fabrics produced were studied, The latter was remarkably affected by its relaxation shrinkage (RS)and hygral expansion (HE) natures. Conclusions are as follows:
