[진동·소음부문] 3축 내구성 시험기의 동시구성 소프트웨어 개발

In the recent day, fatigue life prediction techniques playa major role in the design of components in the ground vehicle industry. Full scale durability testing in the laboratory is an essential of any fatigue life evaluation of components or structure of the automotive vehicle. Component testing is particulary impotant in today's highly competitive industries where the design to reduce weight and production costs must be balanced with the necessity to avoid expensive service failure. Generally, 3-axis durability testing device is used to carry out the fatigue test. In this paper, The operation software for simultaneously driving 3-axis vibration testing device is developed and the displacement of the 3-axis actuator is separately calibrated by LOT. Moreover, the input and output data are displayed in windows of PC controller with real time.
