A numerical simulation on multi-spot pressure tensioning process of circular saw blade

The multi-spot pressure tensioning process of circular saw blade was built by dynamic/explicit solution module of the finite element software called ABAQUS for avoiding non-convergence and improving the computational efficiency. The stress field of circular saw blade during loading process was calculated based on the finite element model. The model which could both meet the requirement of computational efficiency and accuracy was established by adjusting the step time and density of circular saw blade. The unloading process of circular saw blade was built by static/general solution module of ABAQUS using the stress field of loading process calculated by dynamic/explicit finite element method as initial conditions. The tangential tensioning stress field of circular saw blade tensioned by multi-spot pressure which showed the same trend with the measured result was calculated based on the two above-mentioned models. A more ideal distribution of tangential tensioning stress could be produced by the multi-spot pressure tensioning process. The feasibility of multi-spot pressure tensioning process was theoretically proved in this paper.
