Peanut picker is a common peanut harvesting machine. The stripping roll is one of the important parts of the peanut picker. Its stability is an important guarantee for the normal operation of the picker. In this paper, the static and modal analysis of a certain type of stripping roll is carried out by using finite element method. The results show that: under rated working conditions, the maximum equivalent stress of the stripping roll is 52.285 MPa, which is much less than 400 MPa, and material yield failure will not occur. According to modal analysis, the frequency of external interference of the stripping roll can not be close to 56.26 Hz, 57.52 Hz, 60.00 Hz, 118.31 Hz, 144.50 Hz and 147.45 Hz, otherwise resonance hazards will easily occur. Through the analysis, the mechanical characteristics of the stripping roll are reasonably analyzed, and the basis for the follow-up optimization design is provided.
