Abstract: Aiming at the life and the forces inside of elevator traction rope, a strand of 1×19 structure and 8×19 structure of elevator traction rope were researched for mechanical. The force of a single strand of wire rope was analyzed and the strain was got first. Then the mechanical performance of entire rope was analyzed and the model was established by solving the equation of mechanical in Matlab/Simulink. The internal stress of the rope was calculated. Influence of the radius of the single stand wire on contact stress was researched. It also was analyzed and verified by stretch and splits of rope test indirectly. The results indicate that the contact stress of the core stand and the side stand is max, followed by the core inner layers wire of stand, the inner outer wire of strand is min; Experimental result is consistent with the simulation; Contact stress decrease and more uniform as radius of core/ inner/outer wire layers increase which are basis for the after study of the elevator rope.
