The structural characteristics of forklift batteries and speed of calculation

In Ningxia, Inner Mongolia, Shanxi, Shandong, Anhui, Qinghai, Gansu, Fujian and other provinces, the effect was satisfactory. L1 1994, the date of receipt paper dated 2 ugly machines meet the requirements after the calculation speed in the design of the following methods used. Driving Force: F = (N) where, T a motor output torque (Nm), i a ratio. ~ Efficiency, R a wheel rolling radius (m). Walking Resistance: F A (f +0.01 B) W (N) where, w the quality of a forklift truck (kg), slope, f a rolling resistance coefficient. When the slope 00, the driving force F and walking Fr resistance are equal, the motor output torque can be calculated T, then the T is the torque required for maximum speed T = (Maximum speed V: According to the motor characteristic curve When found on the T-motor speed N (1 - pm) v: X60 (km / h) lu. l by the above method to calculate the maximum speed the design and actual value is almost equal. Here we must emphasize, quality of design and calculation of the value of forklift rolling radius R w and the value must be close to the actual value. This Date received 23 January 1995. one by one kohlrabi barrier; Wei, CNC touch of minced meat ~ KLK-G2lTLj Drying Machine Fuzzy control of steam pressure D 5 ☆ Taiwan Fertilizer Department of Economic and Technical Institute of Electrical and Chen Dong Zhangping ------~,--~ cigarette factory processing line key equipment Drying Machine's main task is to achieve the tobacco drying, the moisture content of character homes volumes then process requirements, the processing of the same kind of tobacco, the water should remain the same as KLK-G Drying machine uses steam and hot air drying method countercurrent heat. Its main conclusions from the drying Lang dig tube, drive hot air systems, cooling systems, compressed air system and electrical control system composed of several parts. which electrical control system is composed of hot air temperature control system, roller speed control system, steam pressure control system composed of three separate subsystems, respectively, air temperature, drum speed, vapor pressure, incoming tobacco control flow and moisture fluctuations. steam pressure control system is mainly controlled by analog regulators,[link widoczny dla zalogowanych], here we the intelligent control theory, intelligent fuzzy controller proposed ideas. a steam pressure controller KLK-G cross-paste machine steam pressure Drying negative feedback loop route the steam pressure sensor and transmitter, servo amplifiers, servo motors and steam control Yan and so on. Under normal circumstances, Drying machine imported tobacco sub-flow and constant operation, a constant export of tobacco sub-contractors, Amnesty added part of the steam pressure and feed-forward correction signal to zero. Here the comparison part of the error signal generated by a given value for the vapor pressure signal and the difference between the actual signal. When the input to the control valve of the steam pressure is stable, measured inside the drum Yan vapor pressure and the actual value is equal to the servo amplifier output is zero, the control with the opening of the same. When the steam pressure fluctuation source to compare aspects of the error signal is not equal to zero, after the servo motor servo amplifier to the positive and negative turn, lie and that the width of the opening section of the control. On the other hand, when drying the mouth of the tobacco silk machine water flow and water fluctuations or export of tobacco for some reason, when the deviation from the given value, added to the comparative aspects of steam pressure feedforward correction signal is not zero, more links to the error signal generated by these two correction signals, garlic steam pressure for a given steam pressure feedback signal, and Yan, efficiency and generation of signal. Therefore, we can end this algebra and as The error signal E. steam pressure setpoint, with the machine running Drying vary. In the warm state, Yan lower vapor pressure for a given value by the state to start or automatic preheat state, by the automatically given a higher vapor pressure. garlic steam pressure feedback loop control process, is to ensure that the steam pressure regulator with the output value of Taiwan into the vapor pressure equal to the reference. It is essentially regulated by the ratio of the error signal regulator. For this type of object properties with time delay and without any strict mathematical model of the system, the use of traditional control methods can not fully achieve the desired control effect. If intelligent fuzzy control theory and classical control theory, according to different states of the system to select the appropriate control mode, the system control performance more excellent. fuzzy control are areas of intelligent control is based on fuzzy set theory, fuzzy linguistic variables and fuzzy logic-based computer efficiency of a nonlinear character control. 1.1 determine the input, output, where we used for the characterization of the pressure wire Lang barrel temperature error signal E and the error variation cE as input to control the amount of u (width of door opening) or control changes in the amount of CU as output is 1.2 to determine the control flies (continued on page 44)
