Torsional Vibration in Power Lines of Farm Machinery 630324

Studies of the causes of torsional vibration in implement and tractor combinations have produced definite rules for design which have eliminated torsional vibration or reduced it to acceptable proportions. There are cases where the natural torsional frequency of the system must be altered to reduce the effect of a forcing frequency. This paper discusses both types and presents means for selecting a suitable powerline stiffness when natural torsional frequency of the system must be altered. When powerline stiffness change is necessary, stiffness is usually decreased. Means of decreasing powerline stiffness, as well as the problems encountered, are considered.
