Abstract

To improve the driving smoothness and stability of lunar rover and reduce the vertical dynamic deflection, this paper sets up vibration model for seven degree-of-freedom lunar rover, presents the calculation method for vibration differential equation and frequency response function, and derives the equation for the vertical dynamic deflection of the rover suspension system based on the ascertaining of the input spectral density of road surface. This paper determines the proper range of stiffness of torsion bar spring and damp of the vibration absorber by the calculation of the vertical dynamic deflection of the rover suspension system with Matlab programming
