Abstract

In order to study the cutting force of castor cutter, the cutting performance of castor stalk was improved. The influence factors of cutting mechanical properties were studied by microcomputer controlled electronic universal testing machine. In this paper, the position of castor stalk, moisture content, loading speed as the experimental factors, to study the extent of their impact on the elastic modulus, the result showed that the stalk position of the most significant impact on the elastic modulus, followed by the loading speed. Then, the growth trend of the outer diameter and wall thickness of the castor stalk at different heights from the ground and their effects on the elastic modulus were studied by multivariate design. Experiments showed that the outer diameter and cross-sectional area had great influence on the flexural modulus of stem, and the ratio of wall thickness and wall thickness to outer diameter had little effect on the flexural modulus of stem. This study provides a theoretical basis for later development of castor harvester.
