Responses of the dynamical systems are highly affected by the natural frequencies and it has a huge impact on design and operation of highrise and highspeed elevators. In the present paper, the variational iteration method (VIM) is employed to investigate better understanding the dynamics of elevator cable as a singledegreeoffreedom (SDOF) swing system. Comparisons made among the results of the proposed closedform analytical solution, the traditional numerical iterative time integration solution, and the linearized governing equations confirm the accuracy and efficiency of the proposed approach. Furthermore, based on the results of the proposed closedform solution, the linearization errors in calculating the natural frequencies in different cases are discussed.
