Study On The Performance Of Special Structure Diamond Saw Blade

With the development of architecture, cutting diamond saw blade have broad market prospect. In this paper, several special structure saw are researched by means of finite elements analysis software ANSYS and experiment.1. Those saw blades with holes structure are analyzed by the mode analysis, study the mode characteristic, the ratio of open-hole is presented and given the formula. Based the third strength theory, the saws are analyzed on strength by transient dynamics; they are calculated by thermodynamics principle; the diameter and group count of holes are optimized by optimization theory. The study shows that thermal stress, noise, distortion and vibration of special saw are less than those of conventional saw, its low temperature area increased. In the certain range, decreasing the diameter and group count of holes, the result will be better.2. The saw blades with different width segment or combination structure are analyzed by the mode and thermodynamics analysis by ANSYS. The result shows that the thermal stress, distortion and radiant efficiency of noise are decreased compared with conventional saw.3. By cutting different hardness concrete experiment, the cutting characteristics of the special saw with holes or different width segment have been studied. The cutting force and vibration in axial direction have been analyzed. The result shows that the cutting force of I_8-48 saw is less than conventional saw, the different width saw is more sharp, and the vibration of I_lklz saw is less.The researches illuminate that the reasonable structure parameters is an important method for improving saw cutting performance. It can guide a new saw designs in theory and practice.
