Abstract This paper mainly carries out the vibration analysis of the parallel multi-spring supported rigid-flexible coupling model and proposes a vibration suppression strategy for the rigid-flexible coupling system, and constructs the relevant multi-spring rigid-flexible coupling model. The vibration analysis and coupling coefficient calculation are carried out based on the Adams ANSYS simulation platforms. The vibration suppression method is studied by co-simulation of the Adams and Simulink platforms. The study shows that the rigid-flexible coupling system by multi-springs shows low damping characteristics (damping ratio ζ = 0.0053), and there is a significant resonance risk in the frequency of 5-6 Hz, 50-60 Hz and 70-90 Hz; the spring stiffness has a dominant effect on the coupling effect and the system coupling increases approximately linearly when the stiffness of a single spring changes suddenly; a vibration suppression strategy is proposed, and it is concluded that the vibration effect is the most significant when the energy is concentrated in the area where the spring stiffness changes.
