유압 굴삭기용 위치제어 실린더

다국어 초록 (Multilingual Abstract)

The operation in excavators is somewhat lonely and helplessness due to the repeated working in a narrow space during a long time and operator is easily exposed to the poor circumstances as high noise, vibration, high/low temperature and dust. So it is getting harder to find out the operator of the machine. Moreover, operating fee of excavators is getting higher because of high oil (fuel and hydraulic fluid) price.
Therefore, to improve the working circumstances and excavating efficiency, it is necessary to develop a remote control and automatic function of excavating operation. In order to develop a position detecting cylinder using for its automation, we installed a permanent magnet at regular intervals with switching N and S pole on the part of load surface of a hydraulic cylinder and obtained high output rate by detection of a hall sensor. From this, we solved problems like a weak magnetism level which is generated when we controlled a position of the cylinder and noise problem by increasing the amplification rate of magnetic sensor. At last, we developed a reliable position detecting technology of hydraulic cylinder for excavators.
