“…The equivalent connection stiffness and damping of traction rope between the elevator frame and the tractive sheave are 3 k and 3 c . The rubber stiffness and damping under elevator car are 4 k and 4 c . In addition, 5 k and 5 c are the connection stiffness and damping between the counterweight and the tensioner pulley.…”

“…The vibration of the elevator will cause additional dynamic loads in the traction system and will also shorten the service life of the elevator and precision instruments. Strong vibration will affect the normal operation of the instrument of elevator, so that the elevator can not be accurately leveled, resulting in a safety accident [1,4], Domestic and foreign scholars have carried out extensive and in-depth research on the vibration characteristics of elevator systems from the aspects of experimental analysis, numerical simulation and theoretical analysis, and given some effective methods to improve the comfort and safety of elevator systems [5][6][7][8][9] .…”

The present paper studied on the high-speed traction elevator developed by Dongnan Elevator Co., Ltd. And the seven degrees of freedom differential equations of a highspeed traction elevator are established by the Lagrange approach. The natural frequencies of the elevator system are carried out through model analysis. The harmonic analysis of high-speed traction elevator is carried out to obtain the vibration characteristic of elevator car and determine the considerable impact model frequencies on the dynamic performance of elevator car. The influences of elevator car load, rubber stiffness under elevator car and rubber stiffness under tractor on the vibration characteristics of elevator car are investigated in detail. The conclusions of this paper provide theory basis for the elevator's dynamic design, troubleshooting and structure optimization.

One major challenge in modern elevator construction is the design of systems, which satisfy the requirements of very high buildings. In this sense conventional elevators with mechanical guides came to their application limitations. An opportunity to optimize the passenger traffic in very high buildings and also in very deep mining applications is an elevator system driven by linear motors instead of traction sheave and ropes. This system can be improved by using non-contact electromagnetic guides instead of a conventional mechanical guiding system. The aim of this work is the implementation of a feedback control for such an active magnetic guiding system for an elevator car in a simulation model. At first, an overview over the applied elevator system is presented. Functionality of drive and guiding system is explained. Afterwards, the design of the simulation model and the derivation of a multi variable state control for the elevator car guiding are shown. Finally, results are presented and analyzed, which show the feasibility of the entire elevator system.

“…Unfortunately, these checks are not necessarily based on skill or training, making the process guesswork rather than a science. The increasing importance of precise tensioning in elevators has created significant demand for better diagnostics [26,27,28,30]. To that end, manufacturers have developed a wide variety of measurement solutions [34], as well as dynamic equalizing tools to respond to balance struggles in real time [25].…”

The paper describes the structural design of a laboratory device that allows for presenting operation, simulating work procedures and checking functionality of the elevator “rope sensors” when equalizing different tensile forces in partial ropes of a rope system of traction elevators. The laboratory device is modified for checking operations of commonly used rope sensors. In an overwhelming number of cases, elevator technicians use them for setting up the unequally distributed tensile forces in elevator ropes. The device is equipped with three, mutually attached pulleys, over which the rope is installed. The unknown tensile force in the rope is determined by an “indirect method”, i.e. from the resultant of the forces of the rope bent over the pulleys, which have an effect on the force sensor. The tensile force along the rope axis can be determined numerically, but also experimentally, from the inclination angle of the rope installed on the pulleys, diameter of the pulleys, diameter of the rope and the force detected by the force sensor of the stretched rope. The paper presents experimentally obtained tensile force values at the rope sensor, deduced from stretching the rope. The paper also describes the procedure for determining the measured load in the rope by rope sensors of the SWR, SWK and RMT-1 types based on the variable axial force in the rope.
