摘要:
摘要：通过研究大豆秸秆的力学性能，为大豆收获机、秸秆切割机、残膜回收机等机具的设计提供必要的基础参数数据。采集相同时节的豆秸秆，利用真空干燥箱测定豆秸秆含水率，在万能材料试验机上对大豆秸秆进行剪切、弯曲特性等试验研究，获得了在相同含水率下不同部位和不同加载速度的大豆秸秆的剪切和弯曲力学特性。结果表明：相同加载速度下，根部的剪切应力和弯曲应力比中部和顶部所需的力大；在不同加载速度下，加载速度越大，所需剪切力越小，弯曲力越大。试验所获得的数据，可用于大豆秸秆粉碎装置的设计与研发。
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.
