WIDE BANDSAW BLADE UNDER CUTTING CONDITIONS .1. VIBRATION OF A PLATE MOVING IN ITS PLANE WHILE SUBJECTED TO TANGENTIAL EDGE LOADING

The cutting span of a bandsaw blade is modelled as a moving plate and a simple, yet powerful, method is presented for analyzing its vibratio n when subjected to various in-plane stresses, including stresses due to tangential cutting forces. Time-independent tangential edge-loading couples modes of vibration and can lead to divergent buckling. The ef fects of transport velocity, ''back-crowning'' and ''prestressing'' on the vibration of a moving plate under tangential cutting forces are a lso investigated. Graphical representations of the modes of vibration are presented. (C) 1995 Academic Press Limited
