Modal Analysis of Rhizomatic Chinese Medicinal Plants Digging Colter Basedon ANSYS

摘要

In this paper, the vibration characteristics of the digging colter for the rhizomatic Chinese medicinal plants harvester are researched, and a modal analysis is completed on the ANSYS 11.0. The main modal characteristics of the digging colter are given in the range of the most impressionable frequencies The vibratory response of the structure under internal or external influence are predicted, and the low-orders inherent frequency and the deformation of the system are obtained. The low-order vibration mode of XY side and XZ side are the most possible response modes. The low-order mode of XY side produced a lateral oscillating deformation, and the low-order mode of XZ side produced a bending deformation. The analysis results provide foundations for further theoretical analysis and structural design of the digging colter.
