Based on control system of the belt intelligent transmission system analysis and research, the choice of the principles of PLC of intelligent transport systems and the circuit and the control procedures of control part have been. They meet the system's functionality.
In this paper, CPDP350 using pulsed MIG welding machine, in the two pulse mode, respectively welding current, Arc voltage welding parameters and acquisition welding current and voltage waveforms. Through the current and voltage waveform analysis of different pulse mode parameters on welding and seam welding process of forming, help in the application process to choose a suitable model pulse welding...
This dissertation analyzed and evaluated solar hot water system from the angle of technology and economy. First, it is analyzed that the operating principle and technical specialty of Solar hot water system, which is a kind of energy-efficient and environmental protection hot water system, which is an effective advisable way for heating water, compared with other traditional hot water system. Then,...
After analyzing take-up assembly for belt conveyor, the current flaw that the device has existed is pointed out in this paper. Then the take-up assembly is improved designed. The improved take-up assembly consists of take-up winch system, hydraulic system, electrical control system etc. System mainly through pressure switch controls oil pump electrical machinery's movement and parking, controls system...
The trend of Chinese processing trade transformation from east to the central and western regions has been formed. Facing the fierce competition from other Midwest provinces, wuhan city circle should take their own advantages, find the influential undertake processing trade transfer of related factors, accelerate the development of logistics, perfect bonded logistics functions, expand use of investment...
This paper has discussed the small tractor transmission, which is uneven thickness and box part of complex structure. The small tractor transmission appears several reasons of cold cracks for in the casting process. This paper proposed prevention measures and solutions in order to greatly reduce the rejection rate, by the process, physical and chemical analysis, core materials testing, tensile strength...
This paper has discussed the popular method of control and deeply analyzed the dynamic and static characteristics of the water level based on analyzing the main factors influencing the water level of drum. This paper begins with the balance of heat and substance of water in boiler's bubble and educes the universal mechanism controlling model to describe the water level of boiler and studies the character...
In this paper, the wind resources of twenty four regions of Inner Mongolia were assessed. The wind atlas was presented using the WAsP software based on the wind datas of twenty four regions in Inner Mongolia during 1998-2008, which were provided by the China meteorological date sharing service system. Using the Weibull probability density function of wind speed and Weibull distribution function of...
In this paper, the pneumatic overspeed control mechanism of 300 W wind turbine was design. This paper analyses the operation principle of overspeed control mechanism, and chooses rudder yaw mode, and gives the accurate formulae of back-position-torque of tale vane. This paper points out that the balance-torque of tail vane comes form its aerodynamic force generated by the angle between wind direction...
In order to establish the optimized model of administrative permit, the paper analysed the incidence relation of administrative permit with multi-business. The modeling method of multi-business incidence relation was proposed by using role network theory and relationship function matrix. An instance was showed to introduce the application of the method in multi-business administrative permit system...
The emerging grid infrastructure presents many challenging security issues that demand new access approach due to its inherent heterogeneity, multidomain characteristic and highly dynamic nature. In order to protect the secure sharing and coordinated use of diverse resources in distributed "virtual organizations", fine-grained access control in grid computing is therefore very necessary...
