Abstract EN
Unbalanced vibration of tangential threshing cylinder increased the grain loss, shortened service life of the cylinder, and resulted in structural resonance during the rice threshing process.
In this paper, the vibration amplitude and frequency of tangential threshing cylinder shaft were tested, and the vibration state of tangential threshing cylinder was identified.
The restricted and working modalities of tangential threshing cylinder were solved by ANSYS software.
Then, by comparing the resonance phenomenon between the inherent constraint frequency and the rotation speed frequency, the shaft vibration under the idle condition of tangential threshing cylinder was tested and analyzed.
According to the axial vibration and axial trajectory of the cylinder, the inherent properties and characteristics of unbalanced vibration were revealed.
Test results showed that when the tangential threshing cylinder was at idling and no-load state, the amplitude of vibration in the feed direction of straw flow was -0.049~0.060 mm, and the average vibration amplitude was 0.013 mm.
As rice flowed along the tangential threshing cylinder, the vibration amplitude slightly increased.
The trend and phase of each trajectory were similar, although the amplitude of each trajectory was different.
The tangential threshing cylinder axis trajectory was flat oval.
Unbalanced vibration was induced by the rice stalks in the concave gap.
