Paddy harrow machine used hydraulic actuator system has been changed to the electric actuator system method. Because driving system of the agricultural equipments has been changed to electric power system. Besides, the effort to reduce the tractor machine's horse power is proceeding rapidly. In this paper, pressure, load scale factor and loading force(dynamic, static force) are considered to determine the cylinder diameter of the electric actuator. The algorithms of paddy harrow machine was studied to control and test the components of link by using the PLC diagram. Also, the electric actuator mechanism system was evaluated through the PLC algorithm. These test results can be attributed to select the actuator capacity and to determine the reliability of the electric actuator system

The hydraulic equipments has a high utilization in the many works such as the excavation, planation and crane works in the construction sites. They are an essential equipments in the construction site and the loading & unloading works of the large size objects. In the many parts which are composed of the hydraulic equipments, the main control valve(MCV) is the core of the equipments. The hydraulic energy from the pump controls the direction and the rate of flow and supply the pressure energy to the some actuators by MCV. In spite of the domestically producing of the common control valves, the MCV which used to the domestic equipments is imported the whole quantity. In this study, it is to reverse-engineer the MCV as the first step in the development of the MCV. To analyze the notch of the spool and the flow path and to apply the formula technique, we try to realize the optimal modeling of the MCV.

Wire manufacturing system is consist of several parts performing such as feeding, drawing, straightening, heat treatment, surface finish and winding. Drawing and straightening processes are repetitive tasks and the most of the them are performed discretely. In this study, automatic manufacturing system for medium fine straight wire has been developed. The developed system is operated with continuous processes, so decrease the time cost and increase product quality

This is a thesis about the experiment of comparison characteristic of exhaust gas in the same condition between diesel engine that is equipped turbocharger to increase effectiveness of the engine which is recently used in a lot of industry which requires high power. Resulting of the experiment turbocharger diesel engine according to response power, difference in low speed is not significant, but in high speed, effectiveness of turbocharger diesel engine is almost the same in four turbocharger. In other hand, in exhaust gas experiment, high response power turbocharger model exhausts less NOX, but it doesn’t significantly affect the result when it comes with decreasing of CO2 and effectiveness of similar power characteristic. As a result, the high response power turbocharger diesel engine is economically effective comparing with the low response power turbocharger diesel engine

Within aging rotary painting system for plastic wheel cover, sprayed paint particles caused the quality problem as attached to back surface of the wheel cover by the cyclone vortex in the booth. The purpose of this study is to select the spray conditions to ensure a stable quality of the rotary painting system. For this, simulation for flow characteristics of each spray nozzle have been carried out using ANSYS program, and tested to find the optimum spray condition, such as spray distance, spray pressure and rotation speed by manufactured test apparatus of paint spray. Finally, satisfactory results were obtained by testing with a actual painting system in developed spray conditions.

Carousel type rotating molding machine is a plastics molding method that is adapted to producing relatively large and seamless parts which are partially or totally enclosed. So it is used to produce the big septic tank, storage tray, icebox, central reservation and so on. Rotating molding method are Rock and Roll, Shuttle, Carousel type, etc. In this study, to develop Carousel type rotating molding machine, its 3D model has designed. Also, to confirm the performance of this model, the theoretical and experimental analysis were carried out under condition of shape and structure of rotating unit and heating unit in molding machine
