✦ Synopsis

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. Two cases of parametric excitation are considered: fluctuating tension, and fluctuating tangential cutting force. Only simple parametric resonances are possible in the case of fluctuating tension, while interesting combination resonances are excited by the fluctuating tangential cutting force.

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

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 vi
