Abstract
- For the railway vehicle vertical dynamic model under the effect of damper rubber joint stiffness, there is no reliable and fast method to solve its dynamic response at present. In this paper, to improve the efficiency of numerical analysis, by reducing the degree of freedom of the system and transforming the vibration differential equation, a numerical solution method for railway vehicles vertical dynamic response under the effect of damper rubber joint stiffness is established. Through a case analysis, the variation of vertical random vibration response of railway vehicles with the stiffness of damping rubber joints is studied by using random vibration theory. This study provides an effective solution method for the numerical simulation of railway vehicles dynamic response under the effect of the damping rubber joint stiffness, and provides a guidance for the stiffness design of the damper rubber joints for railway vehicles.
