Dynamics Study and Damping Optimization of Circular Saw Based on Numerical Simulation and Experimental Analysis

Abstract:

Serious vibration and noise exists in the circular saw cutting process. In order to reduce the cutting vibration and noise, this paper uses the finite element numerical calculation and modal testing analysis to study the dynamic characteristics of the circular saw blades, obtain the circular saw’s kinetic parameters, such as each order natural frequency, the main vibration mode and damping ratio, evaluate the circular saw system’s dynamic response. Through the optimization of slotted design and experimental analysis, a circular saw with reasonable structure reduces the maximum vibration displacement of 11.1% which increases the circular saw blades cutting quality, prolongs the service life and reduces the cutting noise.
