Analysis of Road Roughness Reconstruction of Lunar Rover Experiment Road
Determination of the lunar driving road excitation is the basis of analysis of lunar rover vibration. In this paper, initially, the vertical acceleration signals of lunar in two different roads are collected. Based on the obtained vertical acceleration signals, acceleration power spectrums of the signals are solved by the use of AR model. Additionally, displacement power spectrums are obtained according to the acceleration power spectrum. Consequently, on the basis of obtained displacement power spectrums, reappear of road roughness is achieved by the Fourier inverse transformation method. The experiment results suggest that the method can test effectively the road roughness of lunar rover driving. Synchronously the research of this paper can provide input data for the vibration experiment and vibration simulation of lunar rover. The research is the basis of vibration analysis of lunar rover.
