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. |
