Abstract

The governing equations of the high-speed elevator hoisting system with tensioning device were developed employing the generalized Hamlton’s principle considering the horizontal and vertical coupling effect. The motions of the high-speed elevator hoisting system were illustrated to evaluate the proposed mathematical models and solution method. The simulation results show that tensioning device can effectively control the vibration of the hoisting system. On the one hand, analyzing and explaining the reasons that the vibration of the hoisting system can be greatly reduced by compensating rope with tensioning device. On the other hand illustrate that choice of the tensioning device is reasonable to suppress the vibration of hoisting system. The research can provide a constructive way and idea to practical application of vibration controller.
