The Effect of Tensioning and Wheel Tilting on the Torsional and Lateral Fundamental Frequencies of Bandsaw Blades
Keywords:tension stress, frequency prediction, handsaw blades, tensioning, vibration, machining
The effects of wheel tilting and saw tensioning on the natural fundamental frequencies of the lateral and torsional vibration of a stationary sawblade have been studied. Tensioning was found to increase the torsional fundamental frequency, but did not affect the lateral frequency. Wheel tilting, on the other hand, influenced both types of vibration by shifting the lateral fundamental frequency downward and the torsional frequency upward.
In predicting the natural frequencies under operating conditions of a bandmill, only the effect of tensioning on torsional vibration has to be taken into account. The effect of wheel tilting was found to be essentially outside the range of tilting angles normally applied in practice.
