In order to further improve the safety and reliability of elevator traction system transmission,and optimize the stress between wire rope and rope groove,the most important stress component in elevator traction system.Firstly,this study analyzes the structure and failure form of elevator traction system.Then,a new type of elevator triangular traction wire rope and its groove geometry structure are proposed and established.Finally,the finite element model of the contact force between the elevator traction triangular wire rope and the rope groove is established and simulated.The simulation results show that when the elevator load is 1 kN and the twist angles are 12°,16° and 20° respectively,the maximum contact stresses of the traction triangular wire rope are 229.6 MPa,430.5 MPa and 648.6 MPa,respectively.The greater the twist angle,the greater the contact stress of the traction wire rope,and the easier it is to wear and fail.This study provides a theoretical reference for the safe application of triangular strand wire rope in elevator traction system.
