抄録

In wire type sugarcane stripping machine, we analyzed theoretically the deflection of wire, the force acting at the top of wire and the stress at the root of wire during the process of stripping cane leaves.<br>In order to confirm the theory experimentally, we put octagonal ring for force transducer on the place where was at equal distance from upper and lower stripping drums of wire type sugarcane stripping machine. When the stripping drum was rotated slowly, we measured the normal and horizontal forces acting at the top of wire rubbing the plate on octagonal ring.<br>The results obtained were as follows.<br>(1) The normal force acting at the top of wire was larger than the horizontal force.<br>(2) The force acting at the top of wire was the smallest at the initial place where wire came in touch with sugarcane and was the largest at the place where wire separated from sugarcane, obtaining close agreement between the tendency of experimental values and calculated values.<br>(3) If wire was fixed on stripping drum, the stress at the root of wire increased as the length of lap increased. If the length of lap was longer than 25mm, the stress at the root of wire was larger than the fatigue limit of piano wire.
