The power-take-off (p.t.o.) of a tractor is used to drive a wide range of agricultural machinery. In work, the driveline is subjected to different torque inputs depending on the machine, and the task it performs, e.g. cultivation, moving, forage harvesting. A theoretical analysis of the tractor and machine p.t.o. driveline using a simplified model is described. The effect of Hooke's joints, and non-linear elements such as backlash, overload and overrun clutches is calculated by computer simulation. The frequency response curves for the drive-line of a typical 60 kW tractor and drum mower are presented. Field measurements of driveline torque loading experienced in work are described. The data are analysed to provide design information on the torsional vibration behaviour of a range of machines. By a combination of field measurements and theoretical analysis, potential methods of minimising torsional vibration problems at the design stage are discussed. (Wassmann)
