Abstract
Recently, the automotive industry is being developed rapidly. On this, a demand of high quality performancetestmachine is increased too. But it is progressive technology that must be combined hydraulic, mechanic and electronic technologies. To construct this system, the design of oil hydraulic circuit, interface skill between sensor and personal computer, data acquisition & display system and integrated control are very important skill. Moreover, reliable data is obtained with vacuum system and complex heat exchange system. Therefore, in this study, we designed a performancetestmachine by using above key technologies and we also made a integrated PC control system using personal computer which is more progressive and flexible method than PLC control.
