Evaluation of Ride Vibration of Agricultural Tractors(II) - Development of a Measurement and Analysis System of Ride Vibrations -

This study was carried out to develop a measurement and analysis system of ride vibrations of tractors. The system consists of a portable digital computer, a PCL-812 PG interface card for A/D conversion, two accelerometers, two signal conditioners, a DC-AC power inverter and a DC power supplier. The computer programs installed in the system for data acquisition and analysis were also developed. It was intended that the system should be cheap enough to be afforded by college laboratories but reliable in its functions of measurement and analysis. Characteristics of the components and methods used in the system development were discussed.
