Topology Optimization Design on Vibration and Noise of Circular Saw Blades
Slotting is a good way to reduce the vibration and noise of circular saw blade. Optimization of slotting structure for low noise circular saw blades has become important in the recent designs. Altair_Optistruct provides an optimization toolkit to determine the most efficient load path for various constraints. This paper details the application of optimization techniques to reduce vibration and noise of circular saw blade with slots, the finite element model under the load conditions have been established in Hypermesh software, the vibration of peak ground displacement of modal for frequency response can be optimized to obtain maximum reduction, volume fraction range between 0.1 and 0.3 as constrained condition. The approach results have been successfully realized, and the optimization of slotting placement has been obtained.
