An Experimental Study on The Lateral Natural Frequency of Bandsaw Blades

Two solutions for predicting the lateral natural frequency of bandsaw blades are experimentally verified for saw velocity, span length, and tension stress ("strain"). Both solutions are shown to be accurate provided that the effective span length of the guide system, which has been shown for pressure guides to exceed the distance between facing guide edges, is taken into account.It was found that wheel rotation can cause resonance vibration in the backside section of the sawblade, where the blade extending from wheel to wheel is unsupported. This resonance vibration, however, can be avoided by installing a guide midway between the wheels
