Load Fluctuations of Agricultural Equipments

The Torque Fluctuation of a Disk Mower and a Tedder

Abstract

Authers analyzed random load of a disk mower and a tedder by using the stress and frequency analyzer.
As the results, the torque and the frequency of the disk mower and the tedder were shown in Figs. 3 and 4. The relationship between the torque and the frequency was shown by a exponential equation (1). From this equation, the mean torque and the maximum torque of the working disk mower and the tedder are provided in Figs. 6 and 7.
The value of the mean torque is almost the same as those of other reserchers. But the maximum torque is not the same. It depends on the frequency. This results show the necessity to search the relationship between the stress and the frequency for a random load.
