Study on lateral stiffness and parametric sensitivity of high speed elevator traction wire rope

Abstract

In the real service environment of high-speed traction elevator, the horizontal sway of towing wire rope caused by the center of gravity deviation and airflow disturbance seriously affects the comfort of passengers in the elevator. In view of this problem, this paper first establishes the equivalent model of the flexible traction wire rope of high-speed elevator. Secondly, based on the energy method, the lateral stiffness calculation formula of the towing wire ropes is derived, and then compares the stiffness calculation formula derived from the classical stiffness calculation formula to verify the correctness of the proposed stiffness calculation formula. Last but not least, In MATLAB, the regularity of tension force and traction wire rope lift length on the minimum lateral stiffness value and minimum stiffness position is explored. The results show that the tension force is positively correlated with the minimum stiffness value, negatively related to the minimum stiffness position, and the lifting length of the traction wire rope is negatively related to the minimum stiffness value, and the minimum stiffness position is positively correlated.
