Abstract

Abstract

To study the parameters of noise-reduction holes,ϕ960 mm diamond saw blades are selected as examples.Finite element method(FEM)and boundary element method(BEM)are used to analyze the vibration condition of the blades with different noise-reduction holes.The vibration response of FEM are used as the boundary condition of BEM model to calculate the characteristics of sound field and compare the results of saw blades with different noise-reduction holes.The results show that blades with circular holes perform better at low frequency,that those with triangular holes perform better in middle frequency and that those with pentagonal holes perform better at high frequency.It is concluded that blades with pentagonal holes are better considering the entire frequency segment,whose reasonable rotation speed should be 346-378 r/min and 430-456 r/min.
