A backbone curve (natural frequency) is one of the important characteristics of the non-linear vibration, and the establishment of the calculating method is significant. We have been proposed the analytical and computational method to calculate the backbone curve and resonance curve in the non-linear vibration of elastic beam with gap support. We propose here the improved analytical method to calculate the backbone curve where the more reasonable non-linear spring constant k_G is adopted. The validity of the proposed method is verified in comparison with the backbone curve calculated by using the non-linear spring constant k_N which is less reasonable than k_G.
