摘要：Laser shock process for circular saw blade was proposed and analyzed in this paper. The high pressure plasma shock wave generated by strong laser beam was applied to many local areas of circular saw blade to generate local plastic deformation. Resistance strain rosette and static strain acquisition instrument were used for measuring the stress field of laser shocked circular saw blade. The natural frequency of circular saw blade after laser shock process was tested by hammer vibration test method. Based on reasonable simplification and hypothesis, laser shock process for circular saw blade was built by finite element method. The stress field obtained by experiment and theoretical calculation shows that investigated process is feasible. The natural frequencies of laser shocked circular saw blade for nodal diameters N-d = 2 and N-d = 3 are increased which means that the dynamic stability of circular saw blade is enhanced after modification.
