The Analysis of Dynamic Characteristics in Reduction of the Circular Saw Idling Noise
We investigate the natural frequency and the amplitude of circular saw blades during idling. We use four blades in the paper: 1) The traditional circular saw blades, 2) The circular saw blade with damping materials which is distributed in the core of blade, and the circular saw blade has a uniform thickness, 3) Similar to the above one but the circular saw blade has a non-uniform thickness, the damping region is thicker than other region of the circular blade, 4) the circular saw blade with damping material which is distributed around the core of blade by four small circular regions. We adopt the Finite Element Method in our numerical analysis. Our analytical results are very useful for a better design of circular saw blades.
