Tensioning effect modeling of circular saw blade after multi-spot pressure tensioning process

Abstract

Tensioning, as a plastic forming process, is the most important and advanced manufacturing process for circular saw blade. Multi-spot pressure tensioning is a new tensioning method that has been proposed and applied in recent years. However, the effects of process parameters of this method on tensioning effect of circular saw blade have not been systematically studied. This study aimed to examine the effects of loading force and spot distribution on tensioning stress field and natural frequencies of multi-spot pressure tensioned circular saw blade systematically. Both of these were calculated by a combination of dynamic/explicit, static/general, and frequency modules of ABAQUS software. An X-ray stress test validated the simulated tensioning stress field. Results show that loading force and spot distribution have effects on tensioning stress field and natural frequencies of circular saw blades with different extents.
