“…However, there currently exists a vibration control method that does not require these, called thermal stress stiffening method. 15 The method proposed for flexible disks is also applicable to circular saw blades. In this method, in-plane thermal stress is generated by heating the sawblade’s inner boundary to improve its bending stiffness and achieve vibration control.…”

“…Although this method was proposed by Mote and Rahimi 16,17 in the 1980s, it has not been further studied and promoted due to the limitations of the technology at that time. Nowadays the transverse vibration suppression method has been investigated both theoretically and experimentally, 15 and it has been proven to be effective. However, it is still unknown whether this method can be applied in practical engineering and obtain the desired vibration suppression effect.…”

In this paper, a temperature-controlled circular saw is proposed by a thermal stress stiffening method, which provides a novel approach that is easy to implement for suppressing sawblade’s vibration and improving machining quality. In this method, the sawblade’s inner boundary is heated by infrared radiation to generate in-plane thermal stress and improve the sawblade’s bending stiffness. Through theoretical calculation and experiment, it is found that increasing the inner boundary’s temperature can effectively increase the natural frequency of the sawblade’s dominant mode. Considering that the saw blade operates near and far from its resonant speed, four cutting experiments are performed on a same beech wood bar under temperature-controlled or uncontrolled conditions. The transverse vibration of the sawblade is measured by a laser displacement sensor, and the surface topography of the cut workpiece is obtained by a three-dimensional surface topography measuring device. This vibration suppression method significantly reduces the vibration amplitude of the sawblade, and effectively improves the machining quality of the circular saw. The experimental results show that using this method can reduce the defect depth of cutting processing by more than 60% when the sawblade rotates near its resonance speed, and is also effective when resonance does not occur.

This paper conducted the free vibration analysis of a sandwich annular thin plate with whirl motion. The upper and lower faces of the annular plate are made of uniform solid metal, while its core is porous foamed metal reinforced by graphene nanoplatelets (GPLs). Both uniform and non-uniform distributions of GPLs and porosity along the direction of plate thickness which leads to a functionally graded (FG) core are taken into account. The effective material properties including Young’s modulus, Poisson’s ratio and mass density are calculated by employing the Halpin–Tsai model and the rule of mixture, respectively. Based on the Kirchhoff plate theory, the differential equations of motion are derived by applying the Lagrange’s equation. Then, the assumed mode method is utilized to obtain free vibration behaviors of the sandwich annular plate. The finite element method is adopted to verify the present model and vibration analysis. The effects of porosity coefficient, porosity distribution, graphene nanoplatelet (GPL) distribution, graphene nanoplatelet (GPL) weight fraction, graphene nanoplatelet length-to-thickness ratio (GPL-LTR), graphene nanoplatelet length-to-width ratio (GPL-LWR), spinning speed, outer radius-to-thickness ratio and inner radius-to-thickness ratio of the plate, are examined in detail.
