Abstract: The thesis studied the woodworking tension band saw blades by means of the vibration theories,made sure the relationship between tension force and inhesion frequency of its system.It brought forward that the vibration of the band saw blades may predigest to become the chordal vibration and the vibration of the drawn girders,measured its stress date to exchange its tension forces by means of electricity measure method,measured its inhesion frequencies of the system by means of frequency charts analysis method,and its theory results gained the experimental support,calculated its tension forces and tension stresses at the same time.

Key words: band saw blades, tension force, frequency, stress, analysis
