Modeling and Analysis of the Six-wheeled Rocker Lunar Rover Vibration System
Vibration system modeling is the basis of vibration analysis of the lunar rover. In this paper, the six-wheeled rocker lunar rover was taken as the research object Firstly, the vibration system of the lunar rover was simplified. For the convenience of establishing a vibration model and considering the structural symmetry, the tree coupled road roughness inputs were transformed into one independent road roughness input equivalently. And the vibration model of two degree of freedom (DOF) was established. Secondly, a mathematical model was set up based on with the Lagrange equation. The mathematical model was solved using fourth-order Runge-kutta method. Lastly, under the stone road and with the velocity of 200m/h, the displacement of the gravity center the lunar rover was measured. The experimental results fit with the calculation ones. It proved the vibration model was simple and effective.
