✦ Synopsis

The cutting span of a bandsaw blade is modelled as a moving plate and a simple, yet powerful, method is presented for analyzing its vibration 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 effects of transport velocity, ''back-crowning'' and ''prestressing'' on the vibration of a moving plate under tangential cutting forces are also investigated. Graphical representations of the modes of vibration are presented.

Dynamic instability of a moving plate subjected to parametric in-plane forces is analyzed. The extended Galerkin method is used to discretize the differential equation of motion, and the harmonic balance method is employed for investigating the instability regions of the moving plate.

This study provides yet another possible mechanism for instability of bandsaw blades during sawing, namely dynamic instability of a moving plate when subjected to nonconservative tangential edge loading. In previous publications, the effect of non-conservative edge loading has been neglected; only t
