For the study on tension variation characteristics of hoisting wire rope of high speed traction elevator, the hoisting wire rope time-varying model is built in the process of high speed traction elevator ascending and descending, the ideal run curve of elevator ascending and descending is obtained by fitting the quintic polynomial, also served as the input parameter of the time-varying model parameters of the hoisting wire rope tension. Research shows that the hoisting wire rope tension will reach the maximum when the elevator runs evenly. Changes in elevator acceleration can cause a sudden change in tension of the hoisting wire rope. Keywords—High speed elevator; lifting wire rope; tension; changing rule
