The quasi-wavelet method to solve the dynamic response of beams was proposed. Then the method is used for studying the effects of longitudinal resonance on the dynamic stability with the damping effect taken into account. The study shows the longitudinal resonance can lead to a serious dynamic instability, while the damping can improve the stability effectively. These conclusions are coincident with the existing conclusions well. Hence, the feasibility and effectiveness of the quasi-wavelet method is verified.
