Abstract: In this paper, the differential equations of motion of high speed elevator's mechanical systems are derived and a method for solving these equations using KED analysis is proposed. In order to improve the dynamic characteristics of elevators, a method of finding the optimal design variables of a elevator's mechanical system by minimizing the maximum vibration response is also developed. A practical example of the KED analysis and dynamic characteristics optimization of a TKJ£Ô£±£°£°£°£¯£±.£µ-£Ê£Ø£Ã type elevator has been presented. The results are satisfactory.
Keywords: elevator, kineto-elastodynamics, dynamic optimization.
