The stress distribution across the band saw-blade was measured bymethods of stress-strain in this study and the saw-blade vibrations were investigated in the identical accuracy cohditions to determine the relationship between the saw-blade stress distribution and its vibrationResults of the tests have shown that the state diagram of stress distribution across the blade is related to the setting position on thewheels. In the straight span of blade. the proper value of saw-gullet bottom outstriped from wheel rim is about 22mm; in the bending spanof blade, the local high-strain region can be created on the blade neargullet bottom and such high stress Can approach the bending endurance limit of saw steel The stress concentration cracking is easily produced in these regions under the effect of bending pulse circulationof blade. The. average value of vibration amplitude and standard deviation of blade is of significant linear with the tensile stress Theamplitude of vibration is reduced with the increase of the weight strainsystem.
