Abstract:
The project aims to study the mechanical properties of soybean stalks for the design of comb soybean, soybean straw cutting, and plastic film recycling machines and provide the fundamental equipment and mold design data. Vacuum drying oven was to determine the moisture content of soybean stalks, and respectively by using universal material testing machine and test fixture of soybean straw was studied, the characteristics of shear bending, shear, under different test conditions of soybean stalks bending mechanical properties, effects were measured in different position and different loading speed under load - displacement and other parameters bending mechanical properties of shear in the soybean stalks.Under the same loading rate, the shear stress and bending stress of the root are greater than those of the middle and the top.Under different loading speed, the bigger load speed, the smaller shear force and the bigger bending force. The data obtained from the experiment could be used for the design and development of soybean straw crushing device.
