Recently, many studies on application of farming support and agricultural work management system using information and communication technology to management efficiency of agriculture have been progressed and agricultural machinery of high efficiency and high utilization have also been required. This has brought about consideration of the construction of such measuring system as being important that could identify operating information of agricultural vehicle including safety of vehicle body. Rudimentary operating information of agricultural packaging machinery is exactly about the characteristics of motion of vehicle. In order to identify them, 6 degrees of freedom components of vibration acceleration are required. Previous studies on measuring the vibration of vehicle body of 6 degrees of freedom components of vehicle have been through measuring of translational acceleration of translational accelerometer and rotational acceleration of gyro. However, this method has problems in that measuring system is so large and costly that it could not be regularly used in measuring vibration acceleration and identifying operating conditions of vehicle body (Choe, Jung Seob and E. Inoue, 2001; Inoue E. et al., 1990). Therefore, this study aims to examine the usefulness of MEMS (Micro Electro Mechanical System) sensor, a compact and affordable sensor which has recently received attention, for measuring vibration of agricultural vehicle by obtaining serial data of vibration acceleration using an MEMS sensor and translational accelerometer and thereby calculating and comparing RMS (Root Mean Square) and PSD (Power Spectral Density) as a step before construction of measuring system which can always identify operating conditions of agricultural packaging machinery.
