Influence of the Residual Stress on the Critical Rotational Speed of Circular Saw Blades with Different Structures

Abstract:

The circular saw blade is an important tool for wood processing. The controllable residual stress formed by tensioning process has a clear influence on the critical rotational speed of the circular saw blade. Due to the diversification of the circular saw blade structure and tensioning method, the influence of the residual stress field on the critical rotational speed of the circular saw blade should be further studied. In this paper, four types of circular saw blades are built using the finite element method. Circular elastic thermal expansion and annular elastic thermal expansion zones are used to produce a certain distribution of residual stress field for the circular saw blade. The critical rotational speed of circular saw blade with residual stress field is determined using the finite element method and vibration theory. The results of the theoretical analysis show that, when the tangential tensile stress with sufficient value is formed on the outer edge of the four types of circular saw blades, their critical rotational speed is increased compared with those without residual stress, and it is also increased with the increase of the tangential tensile stress.
