Abstract: By FEM module analysis and temperature distribution analysis of diamond saw blade with multi-holes base and different segment width, influence of different hole diameter, hole number and segment width to nature frequency is clear. Adopted single-factor test, sawing force and acoustic emission signal are measured by cutting several kinds of strength concrete in different cutting parameters. The analysis to characters of sawing force and acoustic emission helps to find out optimum structure of diamond saw blade with different segment width, more rational sawing parameter and its adaptability to workpiece material.

Abstract: Finite element mode analysis and structure optimization of several multitude holes structure diamond saw blades are conducted to study vibration and noise of saw blade. Result shows multitude holes structure saw blade has lower natural frequency than conventional saw blade, which conduces decreasing of noise radiant efficiency. Through configuration optimization, it is clear that hole diameter, hole arrange group number and average displacement DMX of Z axes have great effects on saw blade vibration target function. Finally, the analysis to characters of sawing force and vibration by experiment helps to find out optimum structure of diamond saw blade with multitude holes, more rational sawing parameter and its adaptability to work piece material.
