- Abstract
The contact parameters between calcium fruit and comb teeth are the key to the virtual picking test. In this paper, the physical test of free-falling impacting plate on the self-built test bench and the centre rotation composite simulation test of rigid body dynamics were carried out. The relationship between the contact parameters and dynamic characteristics was obtained, and the contact model was optimized. The contact stiffness k=0.868, force index e=1.91 and damping C=5.56E-4 were obtained when the height of the free falling body was 500 mm. The model was applied to lower free-fall simulation test, and the obtained results were in good agreement with the physical test results. The contact model can be used in the subsequent picking simulation.
