【Abstract】 The effects of slots on the characteristics of circular saws were analyzed quantitatively in this paper. The thermal deflection of saw blades with different number and length of slots was measured,and the vibration behaviors of saw blades with different number, length and width of slots were also measured and analyzed. The results show that the number and length of slots influence the thermal deflection and the vibration behaviors of saw blades, the thermal deflection decreases with the increase of the number and length of the slots, and the amplitude of saw blade with 5 slots and 35 mm of the slot length is the lowest in this experiment. The amplitude of the saw blades is the lowest in 2 000～3 000 r/min of the rotational speed and the amplitude of some saw blades increases markedly when the rotate speed exceeds 3 500 r/min or 4 000 r/min.更多还原
