Chopping biomaterials is an energy consuming process where considerable losses occur because of friction and the compaction of the material. The objective of the paper reported here is to show an energy saving chopping cylinder drive mechanism and to analyze the variations in the drive torque of the chopping cylinder. The chopping mechanism consists of a flexible drive mechanism. Field experiments were performed with a chopper fitted with such a mechanism and the components of the drive torque were determined from the results. The random excitation of the flexible drive mechanism (“multikator”) is caused by the variations in the transport of the material to the chopping cylinder. Consequently there are variations in the angular speed of the chopping cylinder. These variations cause the edgewise vibration of the cutting knives and therefore the energy saving effect. The analysis of random components of cutting torque as a function of time could give an advanced method for designing machine parts operated under dynamic load. Therefore, the critical load, or stress can be calculated by the method developed. Furthermore, the lifetime and the breakdown of the machine parts can be predicted.
