The Flattening and Stiffening Effect of Centrifugal Stress on Circular Saw Blades in Different States
Circular saw blades have many states, before and during the sawing process, depending on the different residual stresses and flatness of the circular saw blades. Based on the different states of circular saw blades, the effect of rotating centrifugal stress on the dynamic stability of circular saw blades is different, mainly reflected in flattening and stiffening effects. In this article, three representative states of circular saw blades were chosen and studied. The finite element method was chosen to simulate the deformation behavior of circular saw blades in the three states. The flattening and stiffening effects of centrifugal stress on circular saw blades in the three states were systematically studied. The axial stiffness of the outer edge of circular saw blades is increased with rotating speed. The rotating speed has a flattening effect on the circular saw blade, as a result of a centrifugal stress field. When the circular saw blade is in a different state, there are some differences in the flattening and stiffening effect of centrifugal stress.
期刊介绍：
Forest Products Journal (FPJ) is the source of information for industry leaders, researchers, teachers, students, and everyone interested in today''s forest products industry.
The Forest Products Journal is well respected for publishing high-quality peer-reviewed technical research findings at the applied or practical level that reflect the current state of wood science and technology. Articles suitable as Technical Notes are brief notes (generally 1,200 words or less) that describe new or improved equipment or techniques; report on findings produced as by-products of major studies; or outline progress to date on long-term projects.
