摘要：Laser shock tensioning process for circular saw blade was proposed in this paper. For exploring the stress formation mechanism of circular saw blade after laser shock tensioning process, theoretical model was built based on finite element method, some reasonable simplifications and assumptions. By comparing theoretical and measured results, the theoretical model was proved to be correct and laser shock tensioning process was proved to be feasible. The effects of spot diameter, impact zone radius, and number of circumferential impact zone on tensioning stress field were studied. Simulation results show that reducing spot diameter and extending impact zone are two effective ways for increasing the tangential tensile tensioning stress in the edge of circular saw blade and enhancing tensioning effect. An optimized scheme for laser shock tensioning process can be obtained by the theoretical model.
