Numerical Calculation Method of Deflection Deformation of Rice Stalk

Blog Article

This paper deals with the numerical calculation method of deflection deformation of rice stalks.Due to large deflection of rice stalks caused by reel operation, Ticket it is improper to adopt the conventional formula that is usually used in small deflection calculation to fit rice stalk deformation curves.Therefore, a large deflection calculation formula in combination with Simpson’s formula was utilized to compute flexural rigidity (EI) and to fit curves.

The experiments were conducted under different loads (0.03, 0.04, 0.

05, 0.06, and 0.07 N) on a self-established deflection testing rig to verify this method.

As a result, the measured results corresponded considerably to ones predicted by this method; furthermore, the flexural rigidity was maintained at a stable level under different loads.This study can Womens Sunglasses provide the basis for establishing a complete deformation model of rice plant and can also be applied in deflection calculation of other stalk crops.
