MECHANICAL MODEL OF CERASUS HUMILIS ESTABLISHED BY UNIAXIAL COMPRESSION PHYSICAL TEST AND VIRTUAL SIMULATION

The mechanical parameters of Cerasus humilis are the basic data for subsequent studies on fruit deformation, damage, and movement characteristics during harvesting transportation, but these rarely reported. Relevant whole compression calculated by comparing physical tests virtual simulations. orthogonal rotating combined experimental design was used to arrange simulation tests, with elastic modulus (E), yield limit (Ey), tangent (Et) as influence factors force result. Response surface optimization employed find closest test point force–deformation curve test. pulp follows: E = 0.923 MPa, Ey 0.0897 Et 0.478 MPa. Results show that step not beginning yield, which substantially earlier than strain rate at step. region increased stress in first appeared junction core due concentration. Combining solve fruits is more suitable testing standard sample.
