“…The model should not be too simple, for it could not accurately reflect the actual situation. 8 On the other hand, the model cannot be too complicated because the amount of calculations will be too large or even impossible to solve. In Fig.…”

The problem of randomness of design parameters objectively exists in the high-speed elevator cabin system. The definite and random part of the acceleration response expressions were derived according to perturbation theory and the transverse vibration acceleration response of the observation point was analyzed. The sensitivity expressions of various random parameters to the acceleration response were deduced by solving the random response of expression and comparing the coefficients of various parameters of the random part. The different impacts of various parameters on the acceleration response were analyzed according to the expression of acceleration response sensitivity. Based on the displacement response covariance matrix and random parameter covariance matrix, the standard deviation characteristic of the acceleration response was obtained and analyzed. The results showed that the random parameters made the acceleration response to be more discrete. Additionally, the randomness of the geometrical parameters had the greatest influence on transverse acceleration. The results can provide a reference for anti-vibration design of high-speed elevators and safety assessment.

A coal mine hoisting system includes two parts, one is a constant-length cable system, and the other is a variable-length cable system. In this paper, the nonlinear dynamic modeling of a coal mine hoisting system is established through Hamilton’s principle. The nonlinear partial differential equations of the coal mine hoisting system are discretized into ordinary differential equations by the fourth-order Galerkin truncation. The nonlinear dynamic responses and four key kinematic and structural parameter analysis of the coal mine hoisting system in the acceleration phases, constant velocity phases, and deceleration phases are given. The results show that the axial vibration displacements of the constant-length cable are an order of magnitude smaller than that of the variable-length cable. The load has the greatest effect on the axial vibration displacement of the hoisting cable. Adversely, the speed has the least effect on the axial vibration displacement of the hoisting cable.

Abstract:We investigated the horizontal response of a vertical transportation with nonlinearities under excitation by guide rail deformations. A LQR control strategy was used in order to improve the comfort of passengers. To this end, a magnetorheological damper (MR damper) was used. The control force of the damper is a function of the voltage applied in the coil of the MR damper that is based on the force given by the controller. Numerical simulations were performed to investigate the nonlinear behaviour of the adopted mathematical model. Moreover, other issues such as robustness of the control technique were evaluated considering parametric errors and noise measurement. The results show that the LQR control strategy using MR damper can be effective in reducing the vibration of the vertical transport.Keywords: optimal feedback control; vertical transportation; MR damper; high-speed elevator; parametric uncertainties; wavelet-based scale index; nonlinear model; chaos; LQR control; nonlinear dynamics.
